Two novel heterocyclic diamine monomers: 1,2dihydro2(4aminophenyl)4[4(4aminophenoxy)phenyl](2H)phthalazin1one and 1,2dihydro2(4aminophenyl)4[4(4aminophenoxy)3,5dimethylphenyl](2H) phthalazin1one were successfully synthesized using readily available heterocyclic bisphenollike monomers through two steps in high yield. A series of novel poly(aryl ether amide)s containing the phthalazinone moiety with inherent viscosities of 1.16~1.67 dL/g were prepared by the direct polymerization of the novel diamines and aromatic dicarboxylic acids using triphenyl phosphite and pyridine as condensing agents. The polymers were readily soluble in a variety of solvents such as N,Ndimethylformamide (DMF), N,Ndimethylacetamide (DMAc), dimethylsulfoxide (DMSO), Nmethyl2pyrrolidinone (NMP), and pyridine. The polymers had high glass transition temperatures (T g)in the 291~329℃ range.
