- 摘要: A novel diamine monomer 2H-(4-aminophenyl)-4-[4-(4-aminophenoxy) biphenyl]phthalazinone 1 containing aza hetero cycle was synthesized and utilized for preparation of new high molecular weight aromatic polyamides with various aromatic dicarboxylic acids with the inherent viscosity of 0.50 similar to 1.62 g/dL. These polyamides had rather high glass transition temperatures of 327 similar to 356 degreesC and their structure was confirmed by IR, H-1 NMR and MS. They are readily soluble in polar solvents such as NMP, DMF etc, and easily cast into tough, flexible films.
