| 摘 要： | 合成了一种4，4′-二氨基-4″-羟基三苯甲烷的二胺单体，用该单体分别和芳香性二酐、酯环二酐以及含氟二酐制备了三种含羟基聚酰亚胺，并对其溶解性能和热性能进行了初步研究，发现含羟基二胺单体和含氟二酐生成的聚酰亚胺能溶解在极性非质子溶剂中，且显示出良好的耐热性能，这种聚酰亚胺可通过羧基引入功能基团制备功能性聚酰亚胺。

| Abstract: | 4,4′-diamino-4″-hydroxyphenyl-triphenylmethan was synthesized and polyhydroxyimides (PHI) based on this diamine and benzophenone-3,3′4,4′-tetracarboxylic acid dianhydride (BTDA), 1,2,4-tricarboxy-3-carboxymethylcyclopentane(TCAAH), hexafluoroisopropylidene 2,2-bis(phthalic acid anhydride) (6FDA) were prepared by solution polycondensation followed by thermal cyclization in refluxing xylene. PHI from 6FDA and DHTM is soluble in aprotonic polar organic solvents such as N-methyl 2-pyrrolidone, N,N-dimethyl acetamide, it has glass transition temperature of 248°C and thermal decomposition temperature above 500°C. |
