摘要： 以侧链带有碳碳双键的衣康酸（IA）、衣康酸磺酸钠（IsNa）、十一烯酸（UA）及1,4⁃丁二醇（BDO）为原料，通过酯化缩聚反应制备了结构可控衣康酸类水性聚（衣康酸类丁二醇⁃co⁃十一烯酸丁二醇）酯 （PBIINa⁃UA），该水性聚酯可通过紫外光引发的巯基⁃烯点击反应固化成膜。采用红外光谱仪、核磁共振仪、界面张力仪、电子万能拉力机等对固化膜的结构、界面张力、拉伸强度进行了分析。结果表明，合成的水性聚酯具有一定的自乳化性能，且基于巯基⁃烯点击反应固化所得漆膜相比于传统的热固化漆膜氧阻聚低。当PBIINa⁃UA中磺酸基团与双键物质的量比为1∶10、引发剂质量分数为1.5%时，得到的漆膜性能最佳

Abstract: A new type of waterborne self⁃emulsifying polyester⁃poly was synthesized from itaconic acid (IA), 1,4⁃butanediol (BDO), sodium itaconate (IsNa) and undecylenic acid (UA). (Itaconic acid butylene glycol⁃co⁃undecenoic acid butylene glycol) ester (PBIINa⁃UA), which could be cured into a film by a UV⁃induced thiol⁃ene click reaction. The structure, interfacial tension and tensile strength of the cured film were analyzed by infrared spectrometer, nuclear magnetic resonance instrument, interfacial tension meter and electronic universal tensile machine. The results show that the synthesized aqueous polyester has a certain self⁃emulsification performance, and the paint film obtained by the thiol⁃ene reaction curing has lower oxygen inhibition than the conventional heat curing paint film. When the ratio of sulfonic acid group to double bond in PBIINa⁃UA is 1∶10, and the mass fraction of initiator is 1.5%, the obtained lacquer film get the best performance.
