摘要

Two new routes to polyamides and polyesters were established

based on the polycondensationof new typical active diacylamide of benzotriazole

such as 1

1'-(isophthaloyl) bisbenzotriazole(IPBBT) and 1

1'-(terephthaloyl)bisbenzotriazole (PBBT) with diamines

diols and diphenol underdifferent mild conditions. The N-acylation of polycondensation occurred at room temperaturewithout added catalyst

the O-acylation of polycondensation had to complete in the presence oftriethylamine as a catalyst at 60℃.
