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LiClO_4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~(-4)S/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. Polyethylene oxide with double bond side groups synthesized from ethylene oxide and allyl glycidyl ether was graft copolymerized with styrene and the grafting efficiency was about 50% .The grafting product was purified by IR and 1H NMR The conductivity of the product with LiClO_4 was higher at room temperature, and its conductivity was close to 10 ~ (-4) S / cm at 25 ℃ with PEO content of 70% and EO / Li = 20/1. In addition, the graft copolymer has high emulsifying ability and good phase transfer catalysis in Williamson solid-liquid reaction.
