METHOD FOR STABILIZATION OF WATER SOLUBLE (CO)POLYMERS OF ACRYLAMIDE Russian patent published in 1995 - IPC

Abstract SU 1526158 A1

FIELD: chemistry of high molecular weight compound. SUBSTANCE: 0.0001-0.0025 mass of sodium salt of 2-mercaptobenzothiazole are added during preparing of monomer mass. Said process is carried out before polymerization of acrylamide or before its copolymerization together with acryl monomers. EFFECT: increases stability of aqueous solutions of polymers, retains their viscosity. 1 tbl
