A process for preparing a thermoplastic hydroxy-functionalized polyester comprises contacting a dicarboxylic acid or a mixture of dicarboxylic acids with a diepoxide in a given solvent in the presence of an end-capping agent and a catalyst under conditions sufficient to form the hydroxy-functionalized polyesters or polyethers.
