Definitions
- the invention relates to the field of detergency and in particular to biodegradable detergent compositions. It more particularly describes biodegradable polymers containing branches based on polyacrylates.
- detergent compositions involve a number of chemicals. These must be biodegradable so as not to harm the environment.
- detergent compositions and cleaning agents contain phosphates. These are very effective and relatively non-toxic, however they cause eutrophication of natural aquatic environments.
- the phosphates have been partly replaced in the formulations for detergency by polymers such as polyacrylic acids or copolymers based on acrylic acid and maleic anhydride. Although the polyacrylates currently used do not pose this problem, their lack of rapid biodegradability causes accumulation in the natural environment (Swift, polymer Degradation and Stability 45, 215 - 231, 1994).
- hydrophilic polymers such as polyvinyl alcohol
- acrylic polyacids with an average mass of less than 1000 by weight have better biodegradability than their superior counterparts (Swift, Ecological Assessment of Polymer 15, 291-306, 1997).
- EP 049761 1 describes the preparation of biodegradable terpolymers and compositions containing them. These terpolymers are based on vinyl acetate, acrylic acid and maleic anhydride. They have average masses by weight of less than 20,000. US 5318719 describes a new class of biodegradable materials based on the grafting of polymers containing acid functions on a biodegradable support based on polyoxyalkylene.
- the Applicant has now found an effective solution for preparing biodegradable polymers for detergency.
- biodegradable polymers constituting one of the objects of the invention consist of hydrophilic acrylic polymers carrying carboxylic functions, the structure of which is characterized by a biodegradable core (A) to which at least two polycarboxylic chains (B) are attached. bonds (C) degradable by hydrolysis or by oxidative cleavage.
- A biodegradable core
- B polycarboxylic chains
- These polymers are also characterized by the fact that each polycarboxylic chain has a degree of polymerization which gives it good biodegradability, and which gives the assembly good functional properties with respect to the detergent composition.
- the polymers of the invention have the following general structure:
- Heart A is generally a biodegradable molecule branched or capable of giving rise to at least two branches, chosen from the group containing pentaerythritol, trimethylol propane, ethylene glycol.
- Polymer B is either an acrylic polyacid or a polymer containing acrylic acid and at least one monomer chosen from the group containing: unsaturated carboxylic monomers other than acrylic acid, maleic anhydride, vinyl or acrylic monomers or diene monomers such as isoprene or butadiene.
- B generally has a weight average mass of between 100 and
- the function C linking the polymer B to the biodegradable core is a brittle bond hydrolysable by alkaline or enzymatic route such as an ester, amide, thioester or thioamide bond or breakable by chemical or biological oxidation such as a double or triple bond.
- biodegradable polymers of the invention can be prepared in different ways.
- they are prepared in the following manner:
- the B— X sequence is firstly prepared, taking care to terminate it with a reactive function, by radical polymerization of the monomer (s) in the presence of a reactive transfer agent, in this case a mercaptan. .
- the functionalized sequence is reacted with the core A.
- the respective amounts of A and B are defined so as to have the desired number of branches.
- Another variant of synthesis consists in first modifying the heart so as to prepare:
- the degradation level obtained is evaluated by liquid chromatography under the following conditions:
- the column is calibrated using polyacrylate standards (Polymer Laboratories).
- the degradability of the polymer under the conditions of the test is measured by the displacement of the peak observed in liquid chromatography towards the lower molecular weights.
- the polymer sample is dissolved in a 0.08 M pH 12 borate buffer at a rate of 10 mg of polymer for 10 ml of buffer solution. Each test is then placed under magnetic stirring in a bath thermostatically controlled at the desired temperature for a determined time.
- the analysis is carried out by liquid chromatography (see above) directly on a sample of the reaction medium after neutralization with 0.1 M HCl, at the rate of 1 ml of HCl for 1 ml of sample.
- Control tests are carried out in parallel: - a flask containing only phosphate buffer (2.8 ml) makes it possible to measure the variations in atmospheric pressure, endogenous respiration is measured in a flask containing only phosphate buffer (1, 8 ml) and the yeast suspension (1 ml), respiration due to contaminants possibly present in the acrylate solution is also evaluated by a test comprising the acrylate (0.5 ml) and the phosphate buffer (2.3 ml), the flasks are stirred in a water bath at 30 ° C, the pressure variation measurements due to the appearance of CO2, revealing the metabolism of acrylate by yeast, are carried out every 1 5 minutes.
- Assimilation test complex flora cultures on polyacrylate These cultures are used on a conventional mineral medium (MgS0 4 7H 2 0 3 g; CaCl 2 2H 2 0 0.1 g; NaCl 1 g; FeS0 4 7H 2 0 0.1 g; ZnS0 7H 2 0 0.1 g; CoCI 2 0.1 g; CuS0 4 5H 2 0 10 mg; AI (S0 4 ) 2 12 H 2 0 10 mg; H3BO3 10 mg; Na 2 Mo0 4 2H 2 0 2 mg; qs 1 liter of distilled water) associated with 0.1 M phosphate buffer pH 7 in the proportions 2/98.
- the polyacrylate tested is at a final concentration of 500 ppm.
- the sludge from the purification station * is diluted to a third in 0.1 M phosphate buffer, pH 7, with 100 mg.H of polyacrylate sample to be tested, then the culture is subcultured on a 500 mg medium. H of polyacrylate to be tested.
- the flasks are incubated at 30 ° C in Monod tubes with transverse shaking and subcultured after one week. The cultures then continue for 30 days under the same conditions.
- the principle of this test consists in measuring the capacity of a given polymer to prevent the formation of a precipitate of CaS ⁇ 4 from sodium sulphate and calcium chloride.
- THF tetrahydrofuran
- acrylic acid multifunctional transfer agent
- AIBN Azo bis-
- reaction mixture is degassed by a succession of vacuum and nitrogen cycles, then placed in an oil bath thermostatically controlled at 70 ° C. Polymerization takes place in batch at reflux of the solvent (THF). After 12 hours of reaction, the reaction mixtures are concentrated on a rotary evaporator then precipitated in ethyl ether, filtered (frit No. 5), and dried in an oven under vacuum (5.10 -2 bar) for a minimum of 6 hours.
- BG104 and 106 as CL19 are built on penta-erythritol-tetramercaptopropionate.
- CL17 is built on glycol-dimercaptoacetate.
- CL35 is built on tri methylol propane-tri mercaptoacetate.
- the poly-telomer BG104 was also used as a carbon substrate for Candida tropicalis cultures compared to easily metabolized control glucose and a reference polyacrylate.
- the respiration values are as follows:
- the poly-telomer BG104 Compared to a standard polyacrylate which does not cause respiration, the poly-telomer BG104 has a specific respiration rate close to 18% of that of glucose, which indicates a marked increase in biodegradability.
- the poly-telomer BG104 was used as carbonaceous substrate for cultures of microorganisms originating from sludges from treatment plants, and analyzed by liquid chromatography in a comparative manner after 1 5 days of culture.
- aqueous solutions are prepared from distilled water, to contain the following salts:
- Solution A CaCl2,2H20 64.9 g / 1 + MgCl2 0.5g / l
- the ion concentration is measured by emission spectrometry using the ICP (Inductively Coupled Plasma) technique.
- ICP Inductively Coupled Plasma
