The component of dicarboxylic acid in the polyester is altered and the properties of the polymer are improved.1,3-Benzenedicarboxylic acid,5-sulfo-1,3-dimethyl ester(SIPM) is added to the polyester,giving water-dispersible products. Changing the mole fraction and the water-sensitivity is changed.10%～12% SIPM copolying with dibasic alcohol and dicarboxylic acids can give better water-dispersible polyester. It can be applied in adhesives,coating,sizing agent.
