Sulfur-containing monomers have received special interest from researchers because of their outstanding opticalperformance. Using the reaction between 2-phenylthioethyl-1-mercaptan and p-chloromethylstyrene, a new vinyl monomer4-(2-phenylthioethylthiomethyl)styrene (PTETMSt) was synthesized. Its structure was characterized by FT-IR and NMR.Copolymerization of styrene and PTETMSt was investigated. The data show that poly(styrene-co-PTETMSt) has higher refractive index, lower density and percentage of water absorption. The copolymer can be used on optical materials. 相似文献

热致型光敏液晶高分子在液晶场中光交联反应的研究 总被引：1，自引：0，他引：1
研究了具有肉桂酸酯侧链基的热致型液晶高分子的光交联行为．结果表明，在２０ｍｉｎ紫外光照射的条件下，形成液晶相的液晶高分子膜的光交联凝胶百分率要明显高于尚未形成液晶相的同种高分子膜．对形成液晶相的高分子膜，在环境温度低于液晶各向同性温度Ｔ时，温度对光交联凝胶百分率的影响甚微．这表明，由于液晶高分子中致介单元的聚集和有序排列形成的微区结构也影响了大分子链侧基肉桂酸酯的聚集状态．从而使其光化学性质发生变化． 相似文献
