摘要
环氧树脂(ER)与聚环氧乙烷(PEO)的共混物经水/乙醇萃取后的剩余物为交联ER-PEO非晶共聚物。萃取分析表明,ER/PEO中约有50wt·％的PEO与ER形成ER-PEO交联共聚物。ER/PEO与NaSCN络合后,由于Na^+的配位络合作用,使结晶能力进一步降低。
The structure of the crosslinked copolymers(and/or blends) of epoxy resin/polyethyleneoxide (ER/PEO) and their complexes with sodium thiocyanate after extraction has beenstudied by using WAXD, SAXS, DSC and SEM methods. The r?sults showed that thesamples after extraction have an amorbhous structures of the crosslinked copolymers (ER-PEO). The crystallinity of the complexes ER/PEO-NaSCN was decreased as compared withcorresponding blends ER/PEO, due to the presence of Na ion.
