Abstract: The water-borne technology for polyester is reviewed with using different hydrophilic monomers, including trimellitic anhydride, dimethylmalonic acid, UV curable hyperbranched waterborne polyester, as well as sulphonate monomer. Methods to enhance the water resistant performance of the waterborne polyester and the related theory are summarized. The possible trends in development of waterborne polyester resins are prospected.

摘要： 综述了4种含有不同亲水单体的聚酯水性化技术，包括传统型的以偏苯三酸酐为亲水性单体的水性聚酯、二羟甲基丙酸为亲水性单体的水性聚酯、紫外固化超支化水性聚酯以及磺酸盐型单体的水性聚酯。在此基础上，叙述了提高水性聚酯耐水解稳定性的方法及原理，并指出了水性聚酯的发展趋势。
