摘要
A new polymer-forming monomer, 3,4-bis(4-aminophenyl)-2,5-diphenylpyrrole, was synthesized in three steps starting from 4'-nitrodeoxybenzoin. Tetraphenylpyrrole-containing aromatic polyamides and copolyamides were prepared from the diamine with various aromatic diacid chlorides and from a mixture of the diamine and 4,4'-oxydianiline with terephthaloyl ephthaloyl chloride, respectively. The resultant polymers had inherent viscosities in the 0.3-1.8 dL/g range and were generally soluble in various organic solvents including N,N-dimethylacetamide and m-cresol. They have glass transition temperatures in the range of 306-333-degrees-C and showed no weight loss below 380-degrees-C in both air and nitrogen atmospheres.
