Synthesis and characterizations of soluble co-condensation type polyamides
摘要
Abstract
Co-condensation type polyamides were prepared by using1,2-dihydro-2-(4-aminophenyl)-4- [4-(4-aminophenoxyl) phenyl]-phthalazin-1-one and 4,4′-diamino biphenyl ether or 4,4′-diamino biphenyl methane as the co-diamine monomers and aromatic diacid as the co-condensation monomer. The polyamides were observed to be soluble in strong polar solvents only when the molar ratio of 1,2- dihydro-2- (4-aminophenyl)-4-[4-(4-aminophenoxyl) phenyl]-phthalazin- 1-one and 4,4′-diamino biphenyl ether or 4,4′-diamino biphenyl methane was 10∶0～5∶5. The intrinsic viscosity of soluble polyamides in NMP was observed to be 0.91～1.43 dL/g. The thermal decomposition temperature (5%) of soluble polyam ides in N2 was observed to be about 450 ℃ and almost independent of the struc ture and molar ratio of the co-diamine monomers studied.关键词
