摘　　要：将具有高折光指数的硫和苯环等基团引入含C C化合物的分子结构中制备了单体甲基丙烯酸苯硫酚酯(PTMA),并利用FTIR,1H NMR和HPLC等技术对其结构进行表征.将PTMA作为单体与苯乙烯进行共聚,制备得到含硫透明光学树脂.对其性能测试结果表明,共聚树脂具有较高的可见光透光率,而且随着PTMA质量分数的增加,树脂的折光指数和密度线性增大,冲击强度提高.Benzene ring and sulphur groups were introduced into a compound containing C==C double bonds to prepare a novel monomer S-phenyhhio-methacrylate （PTMA）, the structure of which was characterized by ^1H NMR, FTIR and HPLC. The new kinds of transparent polymeric resins were obtained through the copolymerization of PTMA and styrene. The copolymer resins possessed high refractive indexes with a good transparency. With the content of PTMA increasing, the refractive index of the copolymer resin was enhanced, and the impact resistance was improved.
