ABSTRACT OF THE DISCLOSURE This invention is directed to a process for making ordered ester/carbonate copolymers characterized by comprising the steps of (1) contacting in an organic liquid medium a dihydric organic compound such as bisphenol-A with a carbonate precursor such as phosgene and a diacid halide such as terephthaloyl chloride under conditions such that the carbonate moieties in the resultant intermediate oligomer are formed simultane- ously with or before the formation of ester moieties and (2) contacting this oligomer with additional carbo- nate precursor under conditions sufficient to form the desired ordered ester/carbonate copolymer.
