- 摘要： A series of novel aromatic poly (amide imide)s containing phthalazinone moieties were prepared from 2-(4-aminophenyl)-4-[3-methyl-4-(4-aminophenoxy)-2,3-phthalazinone-1], a novel diamine1 with four diimide-dicarboxylic acids by Yamazaki phosphorylation method with the inherent viscosity of 0.36-0.65 dL/g. These polymers had high glass transition temperatures above 300degreesC and they lost 10% weight between 426similar to475degreesC in N-2. The structure of diamine 1 and the polymers was confirmed by IR H-1 NMR and MS. The obtained polymers were readily soluble in polar solvents such as NMP, m-cresol etc. and easily cast into tough, flexible films. The X-ray indicated that they are all amorphous.
