摘　　要：采用邻甲基取代杂萘联苯型类双酚 4 -( 3-甲基 -4 -羟基苯基 ) -2 ,3-二氮杂萘 -1 -酮 ( DHPZ-o M)与对氯苯腈反应制得二腈化合物 ,进一步水解为二酸 .以此新型二酸与 3种二胺聚合制得的 3种新型聚芳酰胺均具有较高的耐热性能 ,其 Tg 在 2 83～ 31 6℃ ,且易溶于非质子极性溶剂中 ,聚合物的特性粘数为 1 .2 5～1 .58d L/g( 2 5℃ ,NMP) ,拉伸强度为 85～ 90 MPa,断裂伸长率为 7%～ 1 1 % ,拉伸模量为 0 .9～ 1 .3GPa,电阻系数为 1 0 1 4 ～ 1 0 1 6 .Dihydro-2-(4-carboxylphenyl)-4-[4-(4-carboxylphenoxy)-3-methylphenyl]-phthalazin-1-one, a diacid monomer containing phthalazone moiety and arylene dianimes were used to synthesize polyamides. The monomer and polymers were studied by FT-IR, 1H NMR techniques. The polyamides obtained were soluble in polar aprotic solvents such as DMAc, NMP and had inherent viscosity of 1 25~1 58 dL/g (25 ℃, NMP). The T g of the polyamides were above 280℃. The polyamide films had tensile strength 85~90 MPa, elongation at break 7%~11% tensile modulus 0 9~ 1 3 GPa, and the coefficient of electrical resistantce 10 14 ~10 16 .
