【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 5.89×10 15- 9.87×10 15 Ω and the range of volume resistance coefficients is 1.39×10 16-4.09×10 16 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 1H NMR, which are consistent with the designed structure.更多还原
