FIELD: chemistry of polymers, chemical technology.
SUBSTANCE: invention relates to copolymers consisting of monomers comprising acid groups with double bond and other hydrophobic monomeric component used in prophylaxis of inorganic and organic deposits in water-bearing systems. Invention describes a water-soluble copolymer comprising: (a) monoethylene-unsaturated monomers chosen from group consisting of monocarboxylic acids, dicarboxylic acids and sulfoacids that can be neutralized; (b) at least copolymerizable hydrophobic acrylic, monocyclic and/or bicyclic terpene comprising unsaturated double bond wherein terpene hydrocarbon is preferable, and copolymer is prepared by free-radical copolymerization of components (a) and (b) in an aqueous phase. Also, invention describes a method for synthesis of abovementioned copolymer and methods for its using. Invention provides synthesis of nontoxic copolymer used for prevention of deposits in water-bearing systems that can be easily prepared from available components and able to store for a long time without loss of activity.
EFFECT: improved preparing method, valuable properties of copolymers.
