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 arestill crystallizable thotigh the degree of crystallinity has been deeply suppressed owing to thepresence of the non-crystallizable propylene oxide component.However,the LiClO4 adductwas hardly to crystallize especially in fast cooling.A detailed examination on the heating andcooling rate dependence of the Tm,△Hm,Tc,△Hc and cold crystallization phenomenon of thespecimens was made.

Key words: thylene oxide propylene oxide copolymer, polymer solid electrolyte, crystalliza-tion, melting
