摘要： 用DSC研究了环氧乙烷和环氧丙烷共聚物(EO/PO)及其LiClO4复合物的组成与热性能的关系,结果表明,结晶熔融热溶随PO的增加而减少,同时,结晶度下降,电导率上升;O/Li=20的试样在2次升温中产生冷结晶;热历史影响聚合物的热性能。

Abstract: The relationship between the thermal property and con1position of ethylene oxide/propylene oxide copolymer and its complexes with LiClO4 has been studied by DSC. It is found that the conductivity of the copolymer,as well as its salt-complexes was mainly affected by the amorphous portion of the copolymer.

Key words: ethylene oxide, propylene oxide, copolymer, polymer solid-electrolyte, thermalproperty
