| Abstract: | The synthesis and characterization of a series of novel poly(aryl amide-imide)s based on o-diphenyltrimellitic anhydride are described. The poly(aryl amideimide)s having inherent viscosities of 0.39～1.43 dL/g in N-methyl-2-pyrrolidinone at 30℃, were prepared by polymerization with aromatic diamines in N, N-dimethylacetamide and subsequent chemical imidization. All the polymers were amorphous, readily soluble in aprotic polar solvents such as DMAC, NMP, DMF, DMSO, and m-cresol, 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℃. |
| Keywords: | poly(aryl amide imide) synthesis o-diphenyltrimellitic acid |
