| 摘 要： | 研究了磺化聚苯乙烯离聚体／聚（苯乙烯 ４ 乙烯吡啶）共混体系、磺化聚苯醚离聚体／聚（苯乙烯 ４ 乙烯吡啶）共混体系和磺化聚苯醚离聚体／胺化聚苯醚共混体系在氯仿／甲醇混合溶剂中的粘度行为，结果表明，和它们分别对应的不含离子基的共混物相比，这三个共混体系都表现出较高的比浓粘度．这是由于体系中的酸基及其盐和含氮碱基的引入，在共混组分间产生了强烈的离子相互作用，从而导致分子间的缔合，使比浓粘度提高．并讨论了溶剂体系、功能基种类及共混组分的主链结构等因素对这种分子间缔合作用的影响．

| Abstract: | The solution behavior of sulfonated Polystyrene (SPS) ionomer/Poly(styrene co 4 vinylpyridine) (PSVP)、sulfonatded Poly(phenylene oxide) (SPPO) ionomer/PSVP and SPPO ionomer/aminated PPO was investigated.The reduced viscosities of these three series of blends were higher than those of comparable blends not containing ionic groups.These were attributed to the ion interactions resulting from the acid groups (or metal ion) of ionomer and the vinylpyridine groups of PSVP.The effects of solvent,types of functional groups and structure of main chain were discussed. |
