METHOD OF PRODUCING WATER-SOLUBLE TRIMETALLIC SALTS OF ACRYLIC AND METHACRYLIC ACID COPOLYMERS

摘要

FIELD: chemistry.SUBSTANCE: invention relates to synthesis of water-soluble trimetallic salts of acrylic and methacrylic acid copolymers. The method of producing water-soluble trimetallic salts of acrylic and methacrylic acid copolymers involves polymerisation of a mixture of acrylic and methacrylic acid in the presence of potassium persulphate with subsequent addition of a mixture of aqueous solutions of chlorides or sulphates of di- or trivalent metals in amount of 6.802-35.2776 moles and neutralisation of the remaining free acid with aqueous sodium hydroxide solution.EFFECT: obtaining water-soluble salts of copolymers of different composition.1 cl, 20 ex
