摘　　要：通过氯磺化反应、还原反应和低温相转移催化反应合成了一种新型光学树脂单体 4 ,4 -二巯基二苯硫醚双甲基丙烯酸酯 ( MPSDMA) ,成功地将苯环、含硫基团和双键引入光学树脂单体结构中 ;将 MPSDMA分别与甲基丙烯酸甲酯 ( MMA)和苯乙烯 ( St)通过自由基共聚制成透明树脂 ,共聚树脂性能的研究表明该类新型光学树脂具有高折光指数。Benzene ring, groups containing sulphur, and double bond were introduced into the structure of optical resin monomer successfully, and a new kind of optical resin monomer bis[4 (methacryloylthio)phenyl] sulfide(MPSDMA) was synthesized by means of sulfochlorination, reduction, and low temperature phase transfer catalysis reaction. Transparent resins were prepared by copolymerizing MPSDMA with MMA and St respectively, and the study of the properties of those copolymers showed that this new type of optical resins had a high refractive index and high surface hardness.
