Definitions
- the present invention relates to a method for removing transition metals from polymer solutions.
- it involves the removal of transition metal complexes with a content of up to 1000 ppm.
- it involves the removal of transition metal complexes, which mostly contain copper, from polymer solutions after a completed atom transfer radical polymerization.
- Atom transfer radical polymerization (hereinafter referred to as ATRP) is an important process for the preparation of a variety of polymers such as polyacrylates, polymethacrylates or polystyrenes. This type of polymerization has brought the goal of tailor-made polymers a good deal closer.
- the ATRP method was primarily developed by Prof. Matyjaszewski in the 1990s (Matyjaszewski et al., J.Am.Chem.So ⁇ , 1995, 117, p.5614; WO 97/18247; Science, 1996, 272, P.866).
- a particular advantage is that both the molecular weight and the molecular weight distribution can be regulated.
- As a living polymerization it also allows the targeted construction of polymer architectures such as statistical copolymers or block-copolymer structures. Appropriate initiators make it possible, for example, to additionally access unusual block copolymers and star polymers.
- Theoretical foundations of the polymerization mechanism are explained, among others, in Hans Georg Elias, Macromolecules, Volume 1, 6th Edition, Weinheim 1999, p.344.
- metal components can catalyze depolymerization and thus reduce the thermal stability of the polymer - on the other hand, a significant increase in melt or solution viscosity cannot be ruled out by coordinating functional groups of the polymer .
- the ligands introduced with the transition metal can also have undesirable side effects.
- hydrosilylation e.g. hydrosilylation
- an efficient reduction of the ligand concentration in the processing is important.
- processes that involve destruction of the transition metal complex and exclusive removal of the metal are not sufficient for many subsequent reactions or applications. This is especially true since many of these ligands are odor and color intensive.
- a special form of extraction is the aqueous liquid-liquid extraction from polymer solutions.
- a copper catalyst is used in the synthesis of polyphenylene oxide, which is removed from the polymer solution by aqueous extraction after the polymerization (cf. Ullmanns Exyclopedia of Industrial Chemistry , 5th edition 1992, vol. 26 a, p. 606 ff).
- the disadvantage of this method is that many polar polymers act as suspension stabilizers and prevent the two liquid phases from being separated. So For example, these processes cannot be used to work up polymethyl methacrylates.
- Another disadvantage is the very complex transfer of such a process to large-scale production scales.
- the transition metal compound - for example a copper catalyst - is usually separated from polymer solutions by adsorption on aluminum oxide and subsequent precipitation of the polymer in suitable precipitants or by direct precipitation without an adsorption step.
- Very polar solvents such as methanol are particularly suitable as precipitants.
- a corresponding ligand sphere particularly non-polar precipitation media such as hexane or pentane can also be used.
- such an approach is disadvantageous for various reasons. First of all, after the precipitation, the polymer is not in a uniform form, such as granules. For this reason, the separation and thus the further processing is difficult.
- a solid catalyst is separated from the liquid polymer-containing solution.
- the catalyst itself becomes insoluble, for example by oxidation, or is bound to a solid absorbent or to a swollen but insoluble resin before or after the polymerization.
- the liquid polymer-containing phase is separated from the insoluble material by filtration or centrifugation.
- CN 121011 describes a process in which an adsorbent (in particular activated carbon or aluminum oxide) is added to the polymer solution after the ATRP process and then separated off by filtration.
- an adsorbent in particular activated carbon or aluminum oxide
- Another aspect of the present invention was that it should be applicable regardless of polymer properties such as functionalities, glass transition temperature, structure, molecular weight, branching or other possible variations, and these properties should not be changed during the process either.
- Another task was to use the transition metal residues to remove any ligands that may be released or are present in excess anyway from the polymer solution.
- the object was achieved by precipitating the transition metal compound by adding a suitable precipitant and then separating it off by filtration
- the reaction is usually terminated by oxidation of the transition metal. This can be done very simply by introducing atmospheric oxygen or by adding sulfuric acid. In the case of copper as a catalyst, part of the metal complex often fails with this already established procedure. However, this proportion is not sufficient for further processing of the polymer.
- the task of the optimized was solved Catalyst removal by adding sulfur compounds such as mercaptans as a precipitant.
- the residual sulfur fractions can also be removed very easily, almost completely, by means of simple modifications in the filtration. In this way, products are obtained which have no unpleasant odor due to the sulfur compound.
- a great advantage of the present invention is the efficient removal of the transition metal complexes from the solution.
- it is possible to reduce the transition metal content by filtration by at least 80% by weight, preferably by at least 95% by weight and very particularly preferably by at least 99% by weight.
- it is even possible to reduce the transition metal content by more than 99.9% by weight by using the method according to the invention.
- a large number of different inorganic and organic sulfur compounds and mixtures thereof can be used for the precipitation.
- Hydrogen sulfide and / or sulfides such as ammonium sulfide are particularly suitable as inorganic sulfur compounds.
- the precipitants according to the invention are preferably compounds which contain sulfur in organically bound form.
- Particularly preferred organic compounds are mercaptans and / or other functionalized or unfunctionalized compounds which have one or more thiol groups and / or can form corresponding thiol groups under the solution conditions.
- These can be hydrogen sulfide or organic compounds such as thioglycol acetic acid, mercaptopropionic acid, mercaptoethanol, mercaptopropanol, mercaptobutanol, mercaptohexanol, octylthioglycolate, methyl mercaptan, ethyl mercaptan, butyl mercaptan, dodecyl mercaptan, isooctyl mercaptan and tert-daptan.
- Most of the examples listed are commercially available compounds which are used as regulators in free-radical polymerization. However, the present invention cannot be limited to these compounds. Rather, it is crucial that the precipitant used has an -SH group or forms an -SH group under the existing conditions of the polymer solution in situ.
- said compounds can be used as compounds which are known as regulators from free-radical polymerization.
- the advantage of these compounds is their easy availability, their low price and the wide range of possible variations, which enable the precipitation reagents to be optimally adapted to the respective polymerization system.
- Regulators are used in free-radical polymerization to control the molecular weight of the polymers.
- the amount of regulators based on the monomers to be polymerized, is usually given as 0.05% to 5% by weight.
- the amount of the sulfur compound used is based not on the monomers but on the concentration of the transition metal compound in the polymer solution.
- the sulfur-containing precipitants according to the invention are used in 1.5 molar equivalents, preferably 1.2 molar equivalents, particularly preferably below 1.1 molar equivalents and very particularly preferably below 1.05 molar equivalents. It is readily apparent to the person skilled in the art that the mercaptans described, when added to the polymer solution after termination of the polymerization, have no influence on the polymers. This applies in particular to the molecular weight distributions, the molecular weight, functionalities, glass transition temperature or melting temperature in the case of partially crystalline polymers and structures such as branches or block structures.
- Another advantage of the present invention is that the reduction to one or a maximum of two filtration steps means that the polymer solution can be worked up very quickly in comparison to many established systems.
- the precipitation and subsequent filtration take place at a temperature in the range between 0 ° C. and 120 ° C., process parameters in a common range.
- Another area of the invention is the efficient, simultaneous removal of the ligands which are either bound in the transition metal complexes or are freely present in the polymer solution due to excessive use or possible release during the termination of the polymerization. It is very likely that by coordinating the sulfur compound to the metal core, the multifunctional amine ligands often used in ATRP are not decoordinated from the metal center. In this way, a large part of the ligands is precipitated together with the transition metal.
- auxiliaries can be, for example, inorganic compounds such as acidic aluminum oxide, silica, hydrotalcite or other known acidic compounds or mixtures of the same which are insoluble in organic solvents.
- insoluble organic polyacids such as polyacrylic acid or polymethacrylic acid or insoluble polymethacrylates or Polyacrylates with a high acid content or mixtures thereof or mixtures thereof with the inorganic compounds listed above are added.
- the corresponding auxiliaries are only used optionally in the process according to the invention.
- only significantly smaller amounts of these auxiliaries are necessary. Their separation is also limited to an additional filtration step or can also be carried out simultaneously in the same filtration step with the removal of the precipitated transition metal compounds.
- Adsorbents or adsorbent mixtures can be used to reduce the added sulfur compounds and / or ligands. This can be done in parallel or in successive processing steps.
- the adsorbents are known from the prior art, preferably selected from the group consisting of silica and / or aluminum oxide, organic polyacids and activated carbon.
- the concentration of free ligands such as e.g. multifunctional amines can be reduced by adding activated carbon (e.g. Norit SX plus from Norit).
- activated carbon e.g. Norit SX plus from Norit.
- the activated carbon can also be removed in a separate filtration step or in a filtration step which is simultaneous with the transition metal removal.
- the activated carbon is not added to the polymer solution as a solid, but instead is filtered through filters loaded with activated carbon, which are commercially available (e.g. AKS 5 from PaII Seitz Schenk).
- filters loaded with activated carbon which are commercially available (e.g. AKS 5 from PaII Seitz Schenk).
- a combination of the addition of the previously described acidic auxiliaries and activated carbon or the addition of the previously described auxiliaries and the filtration through filters loaded with activated carbon can also be used.
- Another great advantage of the present invention is the possibility of use in aqueous systems. Many transition metal sulfides have almost zero solubility even in water. The system described for removing transition metal complexes can thus also be transferred to emulsion, mini-emulsion, microemulsion and suspension processes.
- a problem of the process according to the invention for removing transition metal compounds and ligands from polymer solutions is the use of the sulfur compounds listed. Portions of corresponding mercapto compounds remaining in the polymer can lead to an odor impairment of the polymer. Impairment of the product color and a restricted range of uses, for example with regard to cosmetic applications, would also be disadvantageous.
- the mercaptans are used only in a minimal excess of 1.5 equivalents, preferably 1.2 equivalents and particularly preferably less than 1.1 equivalents.
- the content of sulfur-containing compounds is additionally minimized by the use of the acidic inorganic and / or organic insoluble auxiliaries and / or activated carbon and / or filters loaded with activated carbon described to remove said ligands without any further work step.
- the present invention relates to the removal of transition metal complexes from all polymer solutions produced by means of the ATRP process.
- the possibilities that result from the ATRP are briefly outlined below. However, these lists are not suitable for describing the ATRP and thus the present invention in a restrictive manner. Rather, they serve to demonstrate the great importance and the versatile application possibilities of the ATRP and thus also the present invention for the processing of corresponding ATRP products:
