As an important kind of optical material,the organic resin attracts more and more people's attention. The refractive index of the organic resin is one of the most important optical properties.Sulfur atom has both higher molar refraction and lower molecular dispersion effect,so introducing sulfur atoms into the molecules is one of the most effective ways to increase the refractive index of optical resin.The results of six types of sulfur-containing resiins,such as heterocyclics sulfones epoxides,sulfides,polyacrylates and polyurethanes,in recent years were analysed.The situation of sulfur-conta...
