FIELD: chemistry. ^ SUBSTANCE: invention relates to synthesis of polymers with high water absorption based on acrylamide and can be used in production of sanitary and hygiene items, dehydrating agents for the coal industry, water-retaining agents for agriculture. Copolymerisation of an aqueous solution of monomers containing acrylamide and a crosslinking agent is carried out in the presence of ammonium persulphate as a radical copolymerisation initiator with the following ratio of components in the solution of monomers, wt %: acrylamide 85-95, guanidine methacrylate 5-15. The crosslinking agent used is guanidine methacrylate. ^ EFFECT: improved quality of hydrogel, reduced consumption of expensive reagents, simplification of synthesis method, improved application properties. ^ 2 tbl, 3 dwg, 3 ex |
