METHOD OF CONTROLLED RADICAL POLYMERIZATION OF ACRYLIC ACID AND ITS SALTS, RESULTING POLYMERS CHARACTERIZED BY LOW POLYDISPERSITY, AND THEIR APPLICATIONS

摘要

FIELD: polymerization processes.;SUBSTANCE: invention provides a method for homopolymerization of acrylic acid and its salts or copolymerization of acrylic acid with one or several water-soluble monomers in solution in presence of suitable organo-sulfurized polymerization degree regulators according to invention. Thus prepared polymers are used as dispersing substances for mineral materials, for paper coatings, and as paper pulp fillers.;EFFECT: reduced polydispersity of polymers and enabled polymerization degree control according to desired industrial application.;32 cl, 16 tbl, 10 ex
