摘要

通过苯乙烯（Ｓ）及甲基丙烯酸正丁酯（ｎＢｍａ）分别与少量的甲基丙烯酸（Ｍａａ）和马来酸酐（Ｍａｎ）共聚，从而在聚苯乙烯（ＰＳ）及聚甲基丙烯酸丁酯（ＰＢｍａ）链上分别引入了功能基因羧酸基和酸酐基，制得共聚物ＳＭａａ、ＢｍａＭａａ、ｓＭａｎ及ＢｍａＭａｎ．通过将这些共聚物分别交换上金属离子制备得相应的离聚物（Ｉｏｎｏｍｅｒ）及其共混物．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，共混物两组分均具有同种（负）电荷时，仍表现明显的增容作用．

Abstract

tyrene (S)

butyl' methacrylate (Bma)

methacrylic acid (SMaa) and maleic anhydrate (SMan) were used to produce copolymers of SMaa

BmaMaa

SMan

and BmaMan with minor components of Maa and Man. The blends of the correspending ionomers of SMaa/BmaMaa and SMan/BmaMan with a series of counter metal ions produced by solvent casting and moulding were examined by DSC and TEM. In the blends both the polymer components possess negative charge. It has ho shown that introducing metal-ions to the blends of SMaa/BmaMaa ap-parently improves the miscibility. This miscibility enhancement dependes on the nature and amount of the counter ions. For the system of SMaa-Na/BmaMaa-Na

even a single phase blend can be produced.
