摘要：
Novel aromatic polyamides, polyimides, and polyureas containing 1,3,5‐triazine rings were pre‐pared by the reaction of 2‐anilino‐4‐aminoanilino‐6‐aminophenyl‐1,3,5‐triazines with aromatic dicarboxylic acid chlorides, pyromellitic dianhydride, and diisocyantes, respectively. All polymers were soluble in polar aprotic solvents such as N,N‐dimethylformamide, N,N‐dimethylacetamide, dimethyl sulfoxide, and pyridine. The glass transition temperatures of polymers were in the range of 220–260°C. The thermal stabilities of polymers were evaluated by thermogravimetric analysis in air. These polymers were stable up to 420°C for polyamides, 470°C for polyimides, and 300°C for polyureas. Copyright © 1990 John Wiley & Sons, Inc.
