Radiation grafting of styrene and acrylonitrile to cellulose and polyethylene

摘要: Abstract Radiation induced graft polymerization is one of the best methods for obtaining material with new properties. In this work, radiation grafting styrene, mixture styrene and acrylonitrile to cellulose polyethylene in presence methanol as a solvent by mutual method discussed. At low dose rate, high yields were obtained from two systems used, due lesser termination free radicals polymer growing recombination primary radicals, resulting longer chain length grafted copolymer. system acrylonitrile, comonomer technique was used controlled homopolymer formation during polymerization. Water uptake decreased increasing yields. Grafted can be molded some extent percent grafting, transparent obtained. By styrene–acrylonitrile density degree crosslinking observed.
