FIELD: polymer production.
SUBSTANCE: invention relates to a method for production of high-molecular weight water-soluble polymers used as flocculant at enterprises of water conditioning, petroleum processing, petrochemistry, iron and nonferrous metallurgy, paper-and-pulp, varnish-and-paint, chemical, and other industries. In particular, invention provides a method for production of high-molecular weight (meth)acrylic anionic flocculant via copolymerization of water-soluble anionic ethylenically unsaturated monomer with nonionic ethylenically unsaturated monomer, the former being salt of (meth)acrylic acids and the latter (meth)acrylic acid amide and ester at salt/amide/ester ratio 100:10:(1-6) or 100:(1-6):10. Proposed method leads to production of high-molecular weight (meth)acrylic anionic flocculant in the form of powder with nearly 100% content of principal substance, which is well dissolved in water.
EFFECT: enhanced efficiency in treatment of various disperse systems (industrial effluents).
