Abstract
FIELD: chemistry of high molecular weight compounds. SUBSTANCE: bicomponent system which contains cobalt (II) acetate and persulfate of alkali metal or of ammonium at their molar ratio 1:0.5-1:60 is used as initiator. Copolymerization of acryl acid or acryl acid and acryl amide with water soluble allyl ether of polysaccharide is carried out in aqueous solution. Said ether has formula [CHO(OH)-(R)-(R)], where RisOH, and Ris O-CH-CH=CH,, x= 0.5-2.5, y=0.05-1.1, z=1.5-3, n=50-3050. The process takes place at temperature being changed during polymerization from 50 to 130 C, concentration of cobalt (II) acetate is (0.05-0.7) •10mol/l, concentration of persulfate of alkali metal or of ammonium is (0.35-3.0) •10mol/l, concentration of said allyl ether of polysaccharide is 0.03-5.0 mass % and that of monomer is 15-40 mass %. EFFECT: simplifies the method.
