FIELD: chemistry.
SUBSTANCE: process of preparing a water insoluble polymer hydrogel is that a copolymerization of an aqueous solution of acrylamide and a crosslinking agent in the presence of a radical initiator of copolymerization of ammonium persulfate at a temperature of 88-93°C for 15-30 minutes. The molar ratio of acrylamide and diallyldimethylammonium chloride is 1:1.0-1.4. The resulting hydrogel was washed with water for 5-10 minutes and dried at a temperature of 80-85°C for 5-6 hours.
EFFECT: invention makes it possible to simplify the technological process of obtaining hydrogel, and improve the properties of the target product.
