摘　　要：作为无机玻璃的替代品,有机光学树脂具有轻质、抗冲击性好、易加工和可调性强等优点。折射率是光学树脂的主要参数之一,折射率的高低可直接影响成品镜片的厚度、美观性和舒适度。在不降低光学树脂综合性能的基础上提升光学树脂折射率一直是该领域的热点和难点,在光学树脂中引入高摩尔折射率的硫元素被认为是最有效和常用的方法之一。本文将含硫光学树脂分为烯烃类、环氧类、环硫类、多环类和聚氨酯类,简要综述了国内外近几年的研究进展,涉及单体合成、单体聚合以及单体结构对光学树脂综合性能影响,系统总结了以上材料的特性及发展。As a substitute for inorganic glass,organic optical resin has the advantages of light mass,good impact resistance,easy processing,and strong adjustability. The refractive index is one of the main parameters of optical resins. The level of refractive index can directly affect the thickness,aesthetics and comfort of the finished lens. Improving the refractive index of optical resins without reducing the overall performance of optical resins has always been a hot and difficult point in this field. The introduction of sulfur with high molar refractive index into optical resins is considered to be one of the most effective and commonly used methods. In this paper,sulfur-containing optical resins are divided into olefins,epoxys,episulfides,sulfur heterocyclic rings,and polyurethanes. The research progress in recent years at home and abroad is briefly reviewed,involving monomer synthesis,monomer polymerization,and the influences of monomer structures on the comprehensive performances of optical resins. The properties and development of the above materials are also analyzed.
