含双键侧基的聚氧乙烯与苯乙烯的接枝共聚物及其产物的性质

Graft Copolymerization of Styrene with Unsaturated Side Groups-Containing Polyoxyethylene and Properties of the Products

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.

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 IR and 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.
