The disadvantage of an aqueous polymer dispersion is that the salt content of the aqueous phase in certain cases, the use of dispersion leads to problems associated with wastewater treatment. In addition, the high content of polymer viscosity is not always quite low, which complicates the technological dispersions.

The task of the invention is to provide an aqueous polymer dispersion having a free of salt aqueous phase while maintaining good processing properties.

As examples of the polymer dispersant include: cellulose derivatives, polyethylene glycol, polypropyleneglycol, the copolymers of ethylvinylbenzene, polyvinylpyridine, polyethyleneimine, polyvinylimidazole, polyvinylsilane, polyvinyl-methylsuccinimide, polyvinyl-1,3-oxazolidin-2, polyvinyl - 2-methylimidazole and copolymers, which in addition to combinations of Monomeric components of the above polymers may contain, for example, the following Monomeric components: maleic acid, acid chloride maleic acid, fumaric acid, taconova acid, acid chloride basis of itaconic acid, (meth)acrylic acid and its salt and (meth)acrylamide connection. Preferably as a polymeric dispersant use a simple polyalkylene ether, for example, polyethylene glycol, polypropyleneglycol or polybutylene ether (1,4).

Particularly preferred as the polymer dispersant use polyelectrolytes, for example, polymers containing Monomeric components, for example, salts of (meth)acrylic acid as the anionic monomer components, or quarternion the methyl chloride derivatives of N,N - dimethylaminoethyl(meth) acrylate, N, N-dimethylaminopropyl(meth)acrylate, N,N-dimethylaminoacetyl-(meth)acrylate or N,N - dimethylaminopropyl(meth)acrylamide. In particular, as a polymeric dispersant use poly(diallyldimethylammonium low molecular weight emulsifiers with an average molecular weight, component < 103D, in the amount of from 0 to 5% by weight polymer dispersion.

When carrying out the proposed method of the above-mentioned monomers are used in an amount of 5 to 80 wt. parts, preferably 10 to 50 wt. parts, based on 100 wt. parts of water as the medium in which the reaction is carried out (hereinafter, the reaction medium). If water-soluble amphiphilic monomers and the monomers used in the form of an aqueous solution, the water content of the solution is in the quantity used as the reaction medium of water. The amount of polymeric dispersant based on 100 wt. parts of water in the reaction medium is 1 to 50 wt. parts, preferably 2 to 40 wt. parts and particularly preferably 5 to 30 wt. parts. To start polymerization using, for example, radical initiators, i.e., polymerization initiators, or high-energy radiation, such as ultraviolet light. As radical initiators are preferably used such as, for example, 2,2'- azobisformamide, 2,2'-azobis(2-aminopropane)dihydrochloride, preferably dissolved in dimethylformamide, potassium persulfate, ammonium, hydrogen peroxide, if necessary in combination with a reducing agent, who scored 10-5- 5 weight. %, preferably 10-4- 1 wt.%, the initiator can be added completely at the beginning of the polymerization or at the beginning of the polymerization add only a portion of the initiator, and the remainder is added in the course of the reaction. Furthermore, the mixture of monomers can be added at the beginning of the polymerization, either wholly or partly with the subsequent addition of the residual quantity in the entire polymerization process. The polymerization temperature is 0 - 100oC, preferably 40 to 55oC. the Polymerization is conducted preferably in an inert gas atmosphere, e.g. in nitrogen atmosphere. The final conversion of the monomers is more than 97%, which usually required 1 - 8 hours of polymerization.

For mixing polymeric dispersant with the obtained water dispersion of the polymer can be used as static or dynamic mixers. While static mixers operate in the create mode turbulence arising in liquid mixtures during the flow through the mixer mode turbulence in the dynamic mixer is created actively.

Preferably use a mixer, such as, for example, propeller, disc, impeller, frame, anchor interfere with the process of mixing creates a slight difference cutoff. During the mixing of the polymer dispersant is preferably added in several portions to the resulting aqueous polymer dispersion. If this continues to be stirred and the viscosity of the mixture is continuously controlled. According to a particularly preferred form of execution of the invention obtained water dispersion of the polymer is heated to a temperature of 30 - 90oC, preferably 40-70oC, so that the viscosity was as low as possible during the mixing process. Then determine the viscosity of the dispersion polymer and obtained by dilution with water 1% solution (in terms of water-soluble polymer).

Given the concentration of polymer and the average molecular weight of the polymer of the above monomer components, offer the aqueous polymer dispersion has a low viscosity compared with the polymer dispersion comprising polymer without hydrophobic Monomeric components. By installing amphiphilic Monomeric components can further reduce the viscosity of an aqueous polymer dispersion. This significantly improves the manufacturability of an aqueous polymer dispersion with a high content of polymer (and thus with a high content of active substance).

By the add is up, allowing more content of the polymer, i.e. the active substance in the proposed variance.

When diluted with water, the aqueous polymer dispersion actual viscosity increases to a very high maximum, and the system becomes transparent. At the same time manifests the thickening action of the dispersed polymer. When the content of polymer of 1%, the viscosity is very high, preferably used dispersant, poly(diallyldimethylammoniumchloride), also serves as an active substance, i.e., as connecting impurities in the circulating water substances and substances that promote flocculation, for example, in the case of coagulation sludge wastewater. A further advantage of the aqueous polymer dispersion is high resistance to shear and storage stability. So, for example, a low viscosity aqueous solution containing polymer 1% retained almost completely after prolonged stirring. The absence of organic solvents ensures safe handling of the variance (not vosplamenyat), as well as environmentally trouble-free use it as a thickener, Tlakula is in the production of paper and/or improving conditions in the soil means. In isolated or dehydrated form of the proposed polymer can also be used as the drying means, for example, in the field of hygiene.

The invention is further illustrated with examples of its implementation. Given the physical data is determined as follows.
