Abstract:
A series of bisamines chain-ex tented by amic acid linkag e and by imide l inkage were prepar ed by r eacting benzo phenone tert racar box ylic dianhydride w ith ppheny lenediamine, 4, 4′-diamino-diphenyl-methane and 4, 4′-diamino dipheny ester . The st ructures of the amic acids and imides w ere characterized by proton nuclear magnet ic resonance and infr ar ed spectr oscopy, and the thermal proper ties o f the amic acids and imides w er e measured by thermog ravimetr ic analy sis and dynamic thermal analysis. T he r esult s of thermal analysis show that the bisamines have g ood thermal stability , and they may be used for the prepar ation o f some heat-resistance polymers.
