Definitions
- the invention relates to a process for removing heteropoly compounds from such compounds containing polyethers, polyesters and polyether esters or their solutions by mixing the same with an ether which is of such a low polarity that its addition in order to separate the heteropoly compound present in the polymer phase in a separate phase leads.
- JP-A-83 028/1983 describes, for example, the polymerization of tetrahydrofuran (THF) in the presence of a carboxylic acid anhydride or halo genids to form polyTHF diesters, using a heteropoly acid as a catalyst.
- THF tetrahydrofuran
- the percentage of HPA catalyst dissolved in the polymer phase is considerable in these reactions and can be up to 1% by weight or more, based on the polymer phase.
- the dissolved catalyst precipitates out of this phase in a separation which only consists of distilling off the unreacted monomer, chain termination reagent (s) and any solvent used, not from, but remains in dissolved form in the polymer. On the one hand, this must be prevented for reasons of quality, on the other hand, for reasons of cost, since heteropolyacids are very expensive, it is desirable to recover most of the catalyst.
- the polymeric compounds mentioned can be composed, for example, of monomers from the group of the cyclic ethers, acetals, diols, higher alcohols and lactones. However, it is also possible to free polymeric compounds consisting of other monomers from dissolved heteropoly compounds by the process according to the invention.
- the molar mass of the polyethers, polyesters and / or polyether esters to be cleaned is not restricted, but is preferably less than 5000.
- the polyether, polyester and / or polyether ester containing the heteropoly compound (s) is used as such or in dissolved form, for example and preferably in the solution obtained in the polymerization.
- the procedure is such that a polymerization mixture with two liquid phases is formed, one being the catalyst phase and the other the monomer / polymer phase.
- a typical monomer / polymer phase such as occurs in the ring opening polymerization of THF to polytetrahydrofuran (PolyTHF) in the presence of water with H 3 PW 12 O 40 as a catalyst in a two-phase polymerization system, is as follows composed (figures in% by weight): 77.3% THF, 21.2% PolyTHF, 1.2% H 3 PW 12 O 40 , 0.3% water.
- a simple ether can have the same or different carbon-containing radicals, the radicals also being able to be connected to one another to form a ring.
- the carbon-containing radicals can be alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl, aralkyl groups, which may be halogen (F, Cl, Br, I) or one or more heteroatoms (N, O, S) containing groups can be substituted.
- Examples include diethyl ether, methyl - tert-butyl ether, di-tert-butyl ether, dibutyl ether, dioctyl ether, dicyclohexyl ether, dibenzyl ether or anisole.
