摘要
本研究测定了由不相溶高分子对聚苯乙烯、聚异丁烯及溶剂环己烷或苯组成的三元体系的浊点曲线、双结点线和联结线。在每一个三元体系中,溶剂对其中一个高分子组分是良溶剂,对另一个则是贫溶剂。结果表明,尽管双结点线的形状和走向主要是取决于高分子组分间的不相溶性,但两平衡相的组成则由溶剂对高分子组分的特性决定。
Cloud-point curves and binodal curves are experimentally deter-mined for the ternary sysetms of a incompatible polymer pair polysty-rene and polyisobutylene in cyclohexane and in benzene.The solventused in each ternary system is good for one polymer component butpoor for the other.The observed phase diagrams reveal that thecompositions of the two equilibriated phases greatly depend on thesolvent properties to the polymer components,though the shapeand direction of binodal curves are mainly determined by the polymerincompatibility.
