摘要: 合成了一种新型芳香二胺双-(4-氨基苯基)-4-(3-甲基-4-苯氧基)-2,3-二氮杂萘-1-酮(1)[2-(4-aminophenyl)-4-(3-methyl-4-phenoxy)-2,3-phthalazinone-1,DAMPP].采用Yamazaki体系,二胺(1)能与多种芳香二酸进行溶液亲核缩聚反应,制得一类新型聚芳醚酰胺,其特性粘度为0.40~0.60dL/g;以MS,FTIR和1HNMR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和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转变温度为598~620K,N2气气氛中10%热质量损失温度在673K以上.聚合物2a~2c的表面电阻系数为3.75×1014~9.87×1015Ω,体积电阻系数为1.39×1016~4.09×1016Ω·cm.聚合物在二甲基甲酰胺、1-甲基吡咯烷酮和间甲酚等极性有机溶剂中可溶解,并经浇注得到透明、韧性薄膜.

Abstract: A novel aromatic diamine 2-(4-aminophenyl)-4-(3-methyl-4-aminophenoxy)-2,3-phthalazinone-1(1, DAMPP) containing aza heterocycle was synthesized in a higher yield starting from 4-(3-methyl-4-hydroxyphenyl)-2,3-phthalazinone-1(OM-HPPZ) via two steps conveniently. Diamine 1 polymerized with three aryl dicarboxylic acids to prepare a series of new aromatic polyamides in a high yield using Yamazaki phosphorylation method. The synthesized polymer has a high molecular weight with the inherent viscosity in the range of 0.40-0.60 dL/g. They exhibited high glass transition temperatures of 598-620 K and good thermostable properties with the 10% weight loss temperature above 673 K(in nitrogen). The range of their surface resistance coefficients is 5.89×1015-9.87×1015 Ω and the range of volume resistance coefficients is 1.39×1016-4.09×1016 Ω·cm. These polymers were readily soluble in polar solvents such as NMP, DMF and m-cresol etc, clear tough films were cast from their DMAc solutions. The structures of diamine 1 and polymers obtained was confirmed by MS, FTIR and 1HNMR, which are consistent with the designed structure.
