环氧乙烷和环氧丙烷共聚物及其盐复合物的结晶与熔融
摘要:
聚环氧乙烷(PEO)及其盐复合物等[1,2]是一类高分子固体电解质,但PEO易结晶,不利于电导率的提高,可用非晶的环氧丙烷(PO)与之共聚抑制其结晶[3]。

Crystallization and Melting Behaviour of Poly(ethylene Oxide-co-Propylene Oxide) and Its LiClO4 Complex
Abstract:
The crystallization and melting behaviour of poly(ethylene oxide-co-propylene ox-ide) and its LiClO4 salt complex were studied. It was found that the plain copolymers are still crystallizable thotigh the degree of crystallinity has been deeply suppressed owing to the presence of the non-crystallizable propylene oxide component. However,the LiClO4 adduct was hardly to crystallize especially in fast cooling. A detailed examination on the heating and cooling rate dependence of the Tm,△Hm,Tc,△Hc and cold crystallization phenomenon of the specimens was made.
