摘要: 由环氧乙烷及烯丙基缩水甘油醚合成含双键侧基的聚氧乙烯用苯乙烯接枝共聚,接枝效率可达50%左右.接枝产物经纯化,用IR及1H NMR表征.该产物与LiClO4的络合物有较高的室温导电率,其PEO含量在70%及EO/Li=20/1时,25℃的导电率接近10-4S/cm.此外,该接枝共聚物有较高的乳化能力.在Williamson固液反应中具有良好的相转移催化作用.

关键词: 接枝共聚物, 两性共聚物, 固体聚合物电解质, 相转移催化剂, 聚氧乙烯

Abstract: Graft copolymerization of styrene with copolymer of ethylene oxide and allyl glycidyl ether was studied.The graft efficiency can reach about 50%.The crude products were purified with extractions and characterized with IRand 1H NMR.The complexes of the graft copolymers with LiClO4 exhibit a conductivity approaching 10-4 S/cm at 25℃ The graft copolymers possess good emulsifying property and phase transfer catalytic property in Williamson reaction.

Key words: Graft copolymer, Amphiphilic copolymer, Solid polymer electrolyte, Phase transfer catalyst, Polyoxyethylene
