Abstract

Radiation polymerization of 2-hydroxyethyl methacrylate-vinyl pyrrolidone-water system at low temperature was studied. The polymerization rate-irradiation temperature curve had a maximum peak at near glass transition temperaure, and it was shifted to the site of high temperature with increasing monomer concentration. The polymerization rate in vinyl pyrrolidone at low temperatures was accelerated by the addition of water. The polymers obtained by radiation polymerization of 2-hydroxyethyl methacrylate-vinyl pyrrolidone-water system at low temperatures were a high hydrophilicity and had porous structure.
