摘　　要：通过熔融法将马来酸酐接枝到聚丁二烯链上制备得到马来酸酐化聚丁二烯(MPB),将MPB用二乙氨基乙醇中和成盐,将水性化溶液作为反应介质,加入过硫酸铵引发MPB和二乙烯基苯(DVB)的聚合,得到DVB改性MPB共聚物的水分散液.实验证明涂膜的室温干燥速度明显加快,固化后的涂层耐水性能优异.通过1HNMR、元素分析、FTIR,DSC,TGA等方法,对共聚物的结构与性能进行了分析.Waterborne maleic polybutadiene（MPB） resin was prepared through thermal addition reaction with maleic anhydride and neutralization using diethylaminoethanol. Copolymerization of DVB（divinylbenzene） with MPB was carried out in water solution utilizing ammonium persulfate as redox initiator and aqueous dispersion of MPB/DVB copolymer was ohmined. Investigations showed that drying rate under room temperature of the aqueous dispersion was enhanced and the film exhibited great water-resistance property. The structure and thermal property of the copolymer was characterized by 1H NMR,Element analysis, TGA,EXSG,and FTIR.
