羧化聚苯醚离聚体/磺化聚苯乙烯离聚体共混体系中离子基团的增容作用

COMPATIBILIZATION BY INTRODUCING IONIC GROUPS IN CARBOXYLATED POLY (PHENYLENE OXIDE) IONOMERS/ SULFONATED POLYSTYRENE IONOMERS BLENDS

用ＤＳＣ方法研究了羧化聚苯醚（ＣＰＰＯ）／磺化聚苯乙烯（ＳＰＳ）、以及它们对应的碱金属离子（Ｌｉ＋、Ｎａ＋、Ｃｓ＋）中和的离聚物共混体系的相容性．结果表明，这一体系具有较宽的相容范围，金属离子的引入使共混体系的相容性有所变化，Ｌｉ＋和Ｃｓ＋能促进相容性，而Ｎａ＋则使相溶性略有减弱．

A broad range of miscibility was observed in blends of carboxylated poly (phenylene oxide) ionomers/sulfonated polystyrene ionomers,Compared with blends containing only one component ionomers,compared with blends containing only one component ionomers.It was suggested that it was because the different ionic groups in different components aggregate miscellaneouslly rather than respectively,which acts as one of driving forces to mix more evenly the components.In addition,the types of cation influence the miscibility.
