摘要 利用不同分子量的聚乙二醇(PEG)与4,4'-亚甲基双(苯基异氰酸酯)(MDI)共聚,然后通过聚乙二醇单甲醚(MPEG)封端制得了聚合物。该聚合物热稳定性良好,符合锂离子电池的使用温度。最后通过溶液法制得了不同的聚合物固态电解质,通过测试所得聚合物固态电解质电导率达到4.5×10-5 S/cm。 Copolymers were synthesized from poly（ethylene glycol）（PEG） and diphenyl-methane-diisocyanate（MDI）, which was terminated by methoxypolyethylene glycols（MPEG）. The copolymer exhibits excellent thermostability, and can be used in the lithium ion battery. At last, solid polymer electrolyte were prepared, its electrolyte conductivity can reach to 4.5 ×10^-5 S/cm.
