PROBLEM TO BE SOLVED: To obtain a polymeric composition capable of producing a high- refractive cured resin, having a very high refractive index and a high transparency, while keeping a high Abbe's number. SOLUTION: This polymeric composition is composed of a thioepoxy compound having one or more disulfide bonds in the molecule, wherein the refractive index (nd) of the cured resin is 1.7 or above. |
