摘要

通过将苯乙烯（Ｓ）及甲基丙烯酸正丁酯（ｎＢｍａ）分别与少量的４－乙烯基吡啶（４－Ｖｐ）自由基共聚，在聚苯乙烯（ＰＳ）及聚甲基丙烯酸丁酯（ＰＢｍａ）链上分别引入了功能基团吡啶基制得共聚物ＳＶｐ和ＢｍａＶｐ．然后将共聚物络合上过渡金属离子或结合上来自羧酸的质子，以制得离聚物及其共混物．这里共混物的两组分均具有正电荷．红外光谱（ＩＲ）、差示扫描量热法（ＤＳＣ）及透射电镜（ＴＥＭ）的研究结果表明，通过配位络合和质子转移而引入两聚合物的同种离子对共混体系有显著的增容作用．

Abstract

he results of compatibilization in blends of similarly-charged ionomers are presented.The blends of SVp/BmaVp (Poly(styrene-co-4-vinyl pyridine))with Vp as a minor component were treated with a series of metal acetates and carboxylic acids

respectively. Based on the coordinated complexation between pyridine rings and the ions and proton-transfer from the the carboxylic acid to pyridine rings. both SVp and BmaVp are charged with positive ions.DSC results show an apparent compatiblization effect of the blends by introducing the ions into the polymer chains

and the level of the effect depends on the nature and amount of the metal ions and the acids.
