摘　　要：用甲苯二异氰酸酯将聚乙二醇及聚丙二醇或遥爪羟基聚苯乙烯偶联成多嵌段共聚物。研究了共聚条件及纯共聚物的表征。这两种共聚均具有良好的乳化性和一定的结晶度,与LiClO_4的络合物有颇高的室温导电率。第一种共聚物有一定的强度和弹性。The multiblock copolymers were synthesized by conolymerization of polyethylene glycol with polypropylene glycol or telechelic hydroxyl polystyrene using 2. 1 toluene diisocyanate as coupling agent. The multiblock copolymers exhibited a certain crystallinity.good emulsifying property and their LiClO4 complexes showed a high room temperature conductivity.
