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
