FIELD: polymers in medicine. SUBSTANCE: acrylamide is copolymerized into hydrogel with cross-linking agent in aqueous solution in presence of redox polymerization initiator, cross-linking agent being a mixture containing 55-65 wt % N, N'-methylene- bis-acrylamide, 10-25% wt % N.N'-octamethylene-bis-acrylamide, and 25-35% tridecaethylene glycol dimethacrylate. EFFECT: increased permeability for connective tissue-forming high-molecular compounds and ensured implant shape stability. 2 cl, 2 tbl, 12 ex
