摘　　要：合成了同时具有光固化基团(双键)和热固化基团(环氧)的高折光紫外光-热双重固化树脂,用红外光谱、核磁共振氢谱、质谱表征了树脂结构。配制了一系列紫外光-热双重固化体系,用红外光谱表征了固化过程特征吸收峰的变化;测试了紫外光-热双重固化膜的凝胶率、吸水率、体积收缩率、折光率和表面水接触角。结果表明,高折光紫外光-热双重固化树脂固化后凝胶率可以达到96.4%以上,吸水率在0.87%以下,体积收缩率在6.87%以下,水接触角在60°左右,为亲水性表面。在相同稀释剂条件下,与双酚A环氧丙烯酸单酯光-热固化膜相比,其折光率由1.3014提高到1.5723。High refractive index W-heat double curable resins （CSEMA）, with both W-curable groups （C= C） and heat-curable groups （epoxy）, were synthesized and characterized by FT-IR, 1H-NMR, MS. A series of W-heat curable systems were prepared, and the change of characteristic absorption peaks of the curing process was characterized by FT-IR. The gel content, water absorption, volume shrinkage, refractive index and water contact angle of W-heat cured films were measured. The results indicate that the gel content of high refractive index UV- heat cured resins can reach 96.4 %, the water absorption rate is below 0.87 %, the volumetric shrinkage is below 6.87%, water contact angle is at about 60＊ for a hydrophilic surface. In the same diluents, compared to the bisphenol A epoxy monoacrylates （EMA） W-heat curable systems, the refractive rate increases from 1. 3014 to 1. 5723.
