Abstract: The copolymer acrylonitrile-methyl methacrylate-poly(ethylene glycol)methyl ether methacrylate and its comb-like gel polymer electrolyte were designed and synthesized.The results indicate that the comb-like copolymers with different component ratios have two glass transfer temperatures,one is the main chain's(about 30—60 ℃),the other is side chain's(between-50——30 ℃).The heat stability of the comb-like copolymer changes with variation of the ratios of acrylonitrile.And the copolymer can be used at 150 ℃.The comb-like gel polymer electrolyte takes advantages of acrylonitrile and poly(ethylene oxide). Its mechanical perporties is very good.And the conductivity of the comb-like gel polymer electrolytes is in the magnitude range of 103 S/cm at room temperature.The electrolyte has a value of practical application.
