    摘要： Aromatic polyesters based on diphenols and iso- and/or terephthalic acid are produced by transesterification of esters of the diphenols with the aromatic dicarboxylic acids in the melt by first reacting the aromatic dicarboxylic acids with a stoichiometric excess of the diphenol esters to form oligomers and then condensing the resulting oligomers to the aromatic polyesters with elimination and removal by distillation of diphenol ester.
