| titleOfInvention | Composition for thioepoxy based optical material having superhigh refractive index and method of preparing the optical material |
| abstract | BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a thioepoxy clock ultrahigh refractive optical material, and in particular, a composition for optical thioepoxy clock optical materials and optical materials in which fumes appearing in a thioepoxide ultrahigh refractive optical material having a refractive index of 1.71 to 1.76 containing sulfur have been solved. It relates to a manufacturing method. In the present invention, in the composition for the thioepoxy optical material comprising a synthetic product of the thioepoxy compound and sulfur, the synthetic product of the thioepoxy compound is 2,3-epoxypropyl (2,3- epithiopropyl) sulfide A thioepoxide ultra-high refractive optical material having a refractive index of 1.71 to 1.76, comprising 1.1 to 3 wt% of a compound, and purified by silica gel chromatography using a silica gel for a flash column having a particle size of 200 to 400 mesh. A composition for use is provided. According to the present invention, the haze appearing in the thioepoxy optical material solves the problem, and it is possible to easily obtain a high-quality lens which is clear and transparent with high thermal stability, light resistance and no polymerization imbalance. |
