一种含硫光学树脂的合成与表征

Synthesis and Characterization of a Kind of Sulphur-Containing Optical Resin

采用低温脱水剂法合成了一种含硫、苯环及双键的化合物甲基丙烯酸苯硫酚酯( TPMA) ,并利用 FTIR、1H- NMR、HPLC等技术进行了结构表征。将其作为一种单体与苯乙烯进行共聚 ,制备得到含硫透明光学树脂。对树脂的性能测试结果表明 ,共聚树脂具有较高的可见光透光率 ,而且随着 TPMA含量的增加 ,树脂的折光指数和密度线性增大 。

A kind of monomer (TPMA) containing sulphur, benzenering and double bond was designed and synthesized, and the structure was characterized by FTIR, 1H NMR and HPLC. Through copolymerized with Styrene, a series of Sulphur containing transparent optical resins were obtained. The properties of the transparent polymer were shown that the copolymerization resins possessed good transmittance, and with increasing of TPMA content, the refractive index and density of the optical resin increased linearly, and the impact resistance heightened markedly.
