摘　　要：采用聚环氧乙烷８００单甲基丙烯酸酯与双ｉ甲基丙烯酸酯共聚，制备了网络链段长度与支链长度相等的“模型接枝网络”。测量了其与ＬｉＣｌＯ＿４络合物在不同温度下的电导率，研究了网络中支链含量与电导率的关系，从而提出了接枝网络中支链对离子传导的作用机制。A ‘model graft network' in Which the length of side chain and network seg-ment is the same, has been synthesized by eopolymerization of polyethylene glycol 800 mo-nomethacrylate and polyethylene glycol 800 bismethacrylate.The conductivities of networks containing LiCIO_4 at varied tomperatures were measured. relationship between con-ductivity and side chain content in networks was studied and contribution of side chain to conductivity was proposed.0
