摘要：

New aromatic polyamides (aramids) having inherent viscosities of 0.5–2.6 dL/g were prepared by the direct polycondensation of 4,4′‐diaminotriphenylamine with various aromatic dicarboxylic acids in N‐methyl‐2‐pyrrolidone using triphenyl phosphite and pyridine as condensing agents. These aramids were amorphous and soluble in a variety of solvents such as N,N‐dimethyl‐acetamide, dimethyl sulfoxide, and pyridine, and afforded transparent and tough films by solvent casting. The glass transition temperatures of these aramids were in the range of 280–310°C, and the 10% weight loss temperatures were above 430°C in air. Copyright © 1990 John Wiley & Sons, Inc.
