Gel-forming (co)polymers of N-vinylsuccinimide, N-vinylsuccinamic and acrylic acids grafted on starch were obtained using an initiating redox system or as a result of 60 Co gamma irradiation. The dependence of the level of sorption properties (co)of polymers relative to bioactive compounds (BAC), their water absorption and swelling on the conditions of the (co) polymerization process has been determined. The ability of composite copolymers to high moisture absorption, binding and prolonged release of BAC and the possibility of their use for biomedical purposes has been established.
