FIELD: chemistry of polymers, more particularly film forming agents in paint industry, treatment of leathers, textile, paper and wood, and manufacture of adhesive compositions for various purposes. SUBSTANCE: claimed process is carried out by water emulsion polymerization of preemulsified (meth)acrylic monomers or mixtures thereof with vinyl monomers in the presence of radical polymerization initiator. Emulsion contains monomers to water phases of 1:0.1-0.7 at preemulsifying stage, and emulsifier is anionic compound of general structure 1: R-O(CHCHO)-XOMe wherein X is S and P; Me is Na, K, NH; R is alkyl and n is 1- 13; R is alkylphenol or dialkylphenol and n is 6-30 or mixture thereof with non-ionic compound of general formula II: R-O(CHCHO)H wherein R is alkylphenol or dialkylphenol and n is 6-100. The resulting dispersions of (Co)polymers contain 0.005-0.01% residual monomers. This makes it possible to handle safely dispersions and compositions based thereof. Besides, dispersions are resistant to mechanical effects and to effects of electrolytes. EFFECT: reduced content of residual monomers in aqueous dispersions of (Co)polymers and higher stability of dispersions. |
