So the poly(ester-imide)s have excellent electrical insulation, good physical and mechanical properties and chemical resistance, meanwhile, the poly(ester-imide)s have good thermal stability,so these polymers have been used in making heat resisting materials and been used in regions of machine or electron or aviation and so on [1-4].
Experimental Materials.Trimellitic anhydride,supplied by aladdin,was dried eight hours under vacuum condition at 150˚C.Aminobenzoic acid and 1,4-butanediol were used as received, toluene and N,Ndimethyl- formamide were reduced-pressure distillation, these chemical reagents were supplied by Chengdu ke long solvent plant.
