A new class of poly(ester-imide-ether) multiblock copolymers was synthesized by transes-terification and meltcopolymerization of dimethyl terephthalate (DMT) and N-(4-carbomethoxyphenyl)-4-(carbomethoxy)-phthalimide withethylene glycol (EG) and polytetramethylene glycol (PTMG). The structure of the above copolymers was characterized by^1H-NMR and IR spectroscopy. Some properties of the coplymers were also examined. It was found that their mechanicalproperties and heat stability, compared with poly(ether-ester) copolymers, were obviously improved.
