FIELD: chemistry of polymers. SUBSTANCE: method involves polymerization of acrylic acid in presence of polyacrylamide, ammonium persulfate, surface-active substance and aqueous diethylene glycol solution. Process is carried out at weight ratio of polyacrylamide:acrylic acid:diethylene glycol: ammonium persulfate: surface-active substance equals to 1.3-1.8:1.67-1.84: 15-20:0.0128-0.0251:0.032-0.054, respectively. EFFECT: higher efficiency.
