摘要

用自由基溶液聚合的方法制备了聚（甲基丙烯酸β─羟乙酯）（ＰＨＥＭＡ）和一系列不同组成的苯乙烯－丙烯酰胺共聚物（ＰＳＡｍ）．利用ＤＳＣ

ＩＲ方法研究了ＰＳＡｍ／ＰＨＥＭＡ共混体系的相容性．观察到不同组成的ＰＳＡｍ与ＰＨＥＭＡ等重量比混合时

只有Ａｍ含量在４７～５７ｍｏｌ％范围内的ＰＳＡｍ与ＰＨＥＭＡ的共混物相容

即共混体系表现出一个“ｍｉｓｃｉｂｉｌｉｔｙｗｉｎｄｏｗ”．应用平均场理论计算了上述共混体系的相互作用参数

结果表明共聚物内不同链段间的拒斥力（ｒｅｐｕｌｓｉｏｎ）是使ＰＳＡｍ／ＰＨＥＭＡ共混体系产生“ｍｉｓｃｉｂｉｌｉｔｙｗｉｎｄｏｗ”的主要原因．

Abstract

opolymers of styrene and acrylamide with different acrylamide content (PSAm) and poly (2-hydroxyethylene methacrylate) (PHEMA) were synthesized by free radical polymerization. The miscibility of PSAm/PHEMA blends was studied with the use of DSC

IR methods. A miscibility window was observed when the amount of acrylamide in the copolymers was between 47 and 57mol%. A mean field theory was employed to analyze the blend system. The result showed that the repulsion of dissimilar segments in the copolymer chain led to the miscibility window of the blends.
