【Abstract】 In this article, a common dianhydride-4,4’-(hexafluoroisopropylidene) diphthalic anhydride(6FDA) and acommon diamine-4,4’-oxydianiline(ODA) were selected to synthesis polyimide, and then, through chloromethylation,active chloromethyl group was introduced into polyimide chain. Many compounds with special functions were selectedto react with above chloromethylated polyimide. Hence we can get many kinds of polyimides with many new functionsThis is a facile modification method to polyimides. In this article we investigate the relationship of chloromethylationratio with reaction conditions. The chloromethylated polyimides were characterized by NMR, IR, DSC, and TGA.更多还原
