| Abstract: | Copolymers, containing 70 mol. % units of acrylamide and 30 mol. % units of acrylic acid or sodium acrylate have been prepared. Hydrogels were received by radiation crosslinking of copolymers in aqua solution. Irradiation dose dependences of values of gel-fraction and absorption degree in distilled water have been determined. It was established that copolymer of acrylamide with sodium acrylate crosslinked more quickly, then copolymer acrylamide with acrylic acid. The absorption degree of copolymer, containing units of sodium acrylate is in ten time more, then the absorption degree of copolymer, containing units of acrylic acid. The absorption degree of crosslinked copolymer increase to 50-60 time during pH solution increasing from 5,5 to 12. |
