Despite progress in the development of biodegradable polyesters, little attention has been given to aliphatic/aromatic copolyesters. Therefore, a series of such copolyesters has been synthesized by polycondensation of succinic acid (SA), dimethyl terephthalate (DMT) and 1,4‐butanediol (BD), and their material characteristics and biodegradability have been examined. The chemical composition of the aliphatic/aromatic copolyesters strongly influences the material characteristics and biodegradability. For the copolyesters with a DMT–BD mole fraction of less than 0.2, an optimum between physical properties and biodegradability seems attainable. © 1999 Society of Chemical Industry
