摘　　要：用聚氧乙烯(PEO)大分子单体与2-乙烯基吡啶(VP)在苯中以偶氮二异丁腈为引发剂共聚,合成了带规整聚氧乙烯(PEO)支链的聚2-乙烯基吡啶(PVP).接枝共聚粗产物经纯化及用IR,1H NMR和膜渗透压计等表征.研究了共聚条件.结果表明,接枝效率可达到56%,相对分子质量可达6×104.该接枝共聚物呈现一定的乳化性及良好的相转移催化性.它与LiClO4或TCNQ络合后呈现离子导电或电子导电性.其混合导电率明显高于离子导电率及电子导电率,即呈现协同效应.Amphiphilic poly（vinyl pyridine） （PVP） with uniform polyoxyethylene （PEO） was synthesized by copolymerization of the PEO macromer with 2-vinyl pyridine in benzene, using AIBN as initiator. The purified copolymer was characterized by IR, 1H NMR and membrane osmometry. The copolymerization conditions were studied. The results showed that the grafting efficiency is able to reach 56 % and molecular weight of the copolyrner can reach 6 ×10^4. The graft copolymer can, exhibit emulsifying ability and good phase transfer catalytic property in the Williamson reaction. The grafc copolymer after complexed wich Li- ClO4 and TCNQ showed ionic conductivity, electronic conductivity and mixed conductivity, respectively. The mixed conductivity showed an obvious synergistic effect.
