A possibility for the transformation of polyphenyl imidates, obtained by polycondensation of bisphenols with imidoyl chlorides of mono- and dicarboxylic acids, into N-phenyl-substituted aromatic polyamides and poly(N-benzoylamines) has been discovered. Such a rearrangement resulted from heating at 260–340 °C for 13–17 h, whereas in diphenyl ether solution at 240 °C for 10–14 h. The polymers synthesized are soluble in organic solvents and possess high stability against thermooxidative destruction.
通过双酚与单羧酸和二羧酸的酰亚胺酰氯缩聚而得到的多苯基酰亚胺酸盐有可能转化为 N-苯基取代的芳香族聚酰胺和聚(N-苯甲酰基胺)。这种重排是在 260-340 °C 下加热 13-17 小时产生的,而在二苯醚溶液中则是在 240 °C 下加热 10-14 小时产生的。
