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．
Sulfonated polystyrene ionomer / poly (styrene 4 vinyl pyridine) blends, sulfonated poly (phenylene ether) ionomer / poly (styrene 4 vinylpyridine) blends and sulfonated The viscosity behavior of the poly (phenylene oxide) ionomer / aminated poly (phenylene ether) blend in a chloroform / methanol mixed solvent showed that the three blends were comparable to their respective non-ionic based blends The system showed a higher viscosity. This is due to the introduction of acid groups and their salts and nitrogenous bases in the system, resulting in strong ionic interactions between the blend components, resulting in intermolecular association and increased reduced viscosity. The effects of solvent system, functional groups and main chain structure of blend components on the intermolecular interaction were discussed.
