Radiation-Chemical Synthesis of Crosslinked Films Based on N-Vinylcaprolactam Copolymers

Radiation-Chemical Synthesis of Crosslinked Films Based on N-Vinylcaprolactam Copolymers

Water-soluble copolymers were obtained by graft copolymerization of N-vinylcaprolactam and 2-hydroxyethyl acrylate on polyvinyl alcohol. The chemical composition of the obtained graft copolymers was determined by IR spectroscopy. Cross-linked films were obtained by radiation treatment of water-solub...

Description
Summary:Water-soluble copolymers were obtained by graft copolymerization of N-vinylcaprolactam and 2-hydroxyethyl acrylate on polyvinyl alcohol. The chemical composition of the obtained graft copolymers was determined by IR spectroscopy. Cross-linked films were obtained by radiation treatment of water-soluble copolymers. To estimate the efficiency of the radiation crosslinking of films, the dependence of the yield of gel fraction on the absorbed dose was studied at different proportions of the initial components. It was established that the yield of the crosslinked fraction increases and the swelling capacity of polymer mesh decreases with increasing 2-hydroxyethyl acrylate content in graft copolymer and absorbed dose.
