摘要

合成了一种新型苯基取代芳香二胺双-(4-胺基苯基)-4-(3-苯基-4-苯氧基)-2

3-二氮杂萘-1-酮(2-(4-aminophenyl)-4-(3-pheny-4-phenoxy)-2

3-phthalazinone-1) (1

DAPPP) .采用Yamazaki体系

二胺单体 1能与各种商品芳香二酸进行溶液亲核缩聚反应

制得了一类新型苯基取代聚芳酰胺

其特性粘度为0.63～0.75dL·g-1;以MS、FT-IR、1H-NMR等分析手段研究了新型二胺单体及其聚合物的结构 ;利用DSC、TGA研究了聚合物的耐热性能

结果表明新型聚芳酰胺具有高的玻璃化温度(320.9～329.9℃ )

氮气氛中10%热失重温度在405.3℃以上

聚合物在二甲基乙酰胺、1-甲基吡咯烷酮和间甲酚等极性有机溶剂中可溶解并浇注得到韧性薄膜.

Abstract

A novel diamine 2-(4-aminophenyl)-4-(3-pheny-4-phenoxy)-2

3-phthalazinone-1 (1

BAPPP) containing aza hetero cyclic was synthesized from 4-(3-phenyl-4-hydroxyphenyl)-2

3-phthalazinone-1 (OP-HPPZ) conveniently．Diamine 1 was utilized to prepare a class of new aromatic polyamides with various aryl dicarboxylic acids using Yamazaki method with high molecular weight．The synthesized polyamides had the inherent viscosity in the range of 0.63～0.75 g dL-1．They exhibited high glass transition temperature of 320.9～329.9℃ and good thermooxidative properties．The polymers were readily soluble in polar solvents such as NMP

DMF and cresol etc and their structure was confirmed by MS

FT-IR and 1H-NMR studies．
