基于新型邻二苯基取代偏苯三酸酐合成了粘度在 0 .39～ 1 .4 3系列聚芳酰胺酰亚胺 ,新型无定型聚合物在极性非质子溶剂 DMAC,NMP,DMF,DMSO等中有良好的溶解性 .其玻璃化转变温度在 2 84～ 336℃ . 5%热失重温度大于4 68℃ .

The synthesis and characterization of a series of novel poly(aryl amideimide)s based on odiphenyltrimellit ic anhydride are described. The poly(aryl amideimide)s having inherent vis cosities of 0.39~1.43 dL/g in Nmethyl2pyrrolidinone at 30℃, w ere prepared by polymerization with aromatic diamines in N, Ndimethylaceta mide and subsequent chemical imidization. All the polymers were amorphous, readi ly soluble in aprotic polar solvents such as DMAC, NMP, DMF, DMSO, and mcresol, and could be cast to form flexible and tough films. The glass transition temperatures were in the range of 284~336℃, and the temperatures for 5% weight loss in nitrogen were above 468℃.
