摘要：

本文先通过缩合反应合成羟端基的二酰亚胺单体, 然后利用亲核缩聚反应, 与4,4′-二氯二苯砜及3,3′-二磺酸钠基-4,4′-二氯二苯砜共聚, 制备聚合物. 该合成路线反应周期短, 对温度和溶剂等条件要求不高, 简便易得.

Abstract:

A series of sulfonated polyimides were synthesized by condensation of bis(p-hydroxylphenyl)-1,4,5,8-naphthalenetetracarboxylic di\|imide(NTDA) with various molar ratios of 3,3′-disulfonate-4,4′-dichlorodiphenylsulfone to 4,4′-dichlorodiphenyl\|sulfone. Both the monomers and the polymers were characterized by FTIR and 1H NMR. All the synthesized polymers have intrinsic viscosities above 0.70, which implies that the polymers have a high molecular weight. The DSC and TGA analysis of the polymers show that all of the polymers have good thermal stabilities. The polymers also  have a good solubility, and could be cast into tough membranes. Some properties of the polymer membranes were also studied.

Key words: Sulfonation; Polyimide; NTDA; Fuel Cell; Proton exchange membrane
