Definitions
- the present invention relates to salt-free aqueous dispersions of water-soluble copolymers based on cationic monomers, to the preparation of these dispersions and to their applications.
- the water-soluble polymers are used for different applications and, in particular, as flocculants for the treatment of urban, waste and industrial water, the dehydration of the sludge generated, as thickeners and soil treatment agents.
- aqueous systems of such water-soluble polymers with a high dry extract are gelatinous and have very high viscosities, which make their handling and storage difficult.
- the problem posed to a person skilled in the art is the production of such aqueous systems but having both a high dry extract and a low viscosity.
- Conventional processes for the synthesis of these polymers include solution, reverse suspension and reverse emulsion polymerization.
- Solution polymerization and reverse suspension polymerization lead to powdered products which have the disadvantage of generating dust at the time of use, being difficult to dissolve in water and being unable to train aqueous solutions of high concentration polymers which can be easily handled.
- these two methods have a disadvantage in terms of productivity, on the one hand because of the low concentration of monomer used during the polymerization, and, d 'on the other hand, because of a drying and / or grinding step inducing an increase in the cycle time and an additional cost of energy consumption.
- the reverse emulsion process which has been known for about two decades leads to a product having a polluting organic solvent.
- European patent EP-B-170 394 describes a dispersion of polymer gel particles larger than 20 ⁇ m in a solution of dispersant of poly (sodium acrylic) or of poly (diallyldimethylammonium chloride).
- this product has the disadvantage of having a high viscosity after a long storage period, the viscosity can only be reduced after shearing or stirring.
- European patent applications EP-A-183,466 and EP-A-525,751 American patents US-A-4,929,655 and US-A-5,006,590, and European patent application EP-A-657,478 propose the case of precipitating polymerization in a saline medium of water-soluble monomers, including the polymer precipitates in the form of particles, then is dispersed by means of agitation and stabilized by low-mass polymer dispersants, which are soluble in saline medium. Furthermore, these particles are difficult to stabilize because of their large size (2-50 ⁇ m).
- dispersant two approaches can be envisaged to achieve this stabilization objective: on the one hand by viscosifying the continuous phase through the associative effects provided by the dispersant to avoid sedimentation of the particles, and, on the other hand, promoting effective adsorption of the dispersant on the surface of the particles for better efficiency as a protective colloid, to avoid coalescence of the particles.
- the hydrophobic units present in the structure of the dispersant can greatly contribute to this.
- These dispersants must have low masses, to ensure their solubility in a saline aqueous medium and have cationic functions necessary for flocculation.
- the typical dispersants for these polymerizations are poly (diallyldimethylammonium chloride) or the copolymer of diallyldimethylammonium chloride / (meth) acryloxyethyl-dimethylhexadecylammonium chloride (cf. European patent application EP-A-657,478). In the latter case, it is described that the associative nature can be ensured by the alkyl chains of (meth) acryloxyethyldimethylhexadecyl chloride. ammonium.
- this dispersant takes place in an aqueous medium, thus only allowing the use of the second comonomer which, admittedly, is less hydrophilic than diallyldimethylammonium chloride, but must be water-soluble. This point considerably limits the hydrophobic nature of these dispersing copolymers. It is important to specify that an increase in the hydrophobic character should make it possible to obtain an improved fluidity dispersion.
- cationic or amphoteric copolymers are obtained by polymerizing in the presence of dispersant, water and salts, a mixture of water-soluble monomers.
- the typical monomer mixture for this type of polymerization consists of
- EP-A-0 717 056 claims dispersions of amphoteric water-soluble polymers based on cationic monomers, including (meth) acryloxyethyldimethyldimethyl benzyl ammonium chloride, and anionics (acrylic acid), synthesized in the presence of dispersant.
- cationic monomers including (meth) acryloxyethyldimethyldimethyl benzyl ammonium chloride, and anionics (acrylic acid), synthesized in the presence of dispersant.
- salt can limit the use of these dispersions for certain applications (thickeners or agents facilitating the cleaning of the textile for example).
- German patent application DE-A-4 216 167 and American patent US-A-5 403 883 describe a technique for obtaining low-viscosity salt-free dispersions by polymerization in the presence of the dispersant poly (diallyldimethylammonium chloride), of a mixture of hydrophilic, hydrophobic and optionally amphiphilic monomers.
- European patent application EP-A-0 670 333 describes dispersions of crosslinked polymers obtained by adding a crosslinking agent such as N-methylol acrylamide or N, -methylene bisacrylamide to the mixture of monomers to be polymerized. .
- Post-addition of the same dispersant allows a reduction in the viscosity of the systems described above (Canadian Patent No. 3,123,460). However, it has the effect of increasing the level of dispersant and leading to a dispersion having a low level of dispersed polymer.
