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.

关 键 词:离聚物,共混物,相容性,质子转移,配位络合,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.
Keywords:Ionomer  Blend  Miscibility  Proton-transfer  Coordinated complexation  Compatibilization
