STUDIES OF ACTIVE DIACYLAMIDES OF BENZOTRIAZOLE Ⅰ. SYNTHESIS OF POLYAMIDES AND POLYESTERS*
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℃.
