| titleOfInvention | Polymerization regulators and compositions for resin |
| abstract | In the present invention, an episulfide compound having, in one molecule,nat least one epithio structure represented by the following Formula 2:n nwherein R 5 to R 8 , Y, p, and q are as defined in the specification, nis polymerized in the presence of a halide of a 13-16 group element of the longnperiodic table and/or a polymerization regulator represented by the followingnFormula 1:n nwherein R 1 to R 4 , X and m are as defined in the specification, nto produce a cured resin suitable as optical materials. By using thenpolymerization regulator, the polymerization rate of the episulfide compoundncan be suitably regulated to obtain a cured resin with less defect such as opticalndistortion, striae, coloring and separation from mold during the polymerization.nBy using the halide, the increase in the viscosity of the starting compositionnduring the storage or the casting operation can be prevented, in particular, thenincrease in the viscosity by the spontaneous polymerization after adding anpolymerization catalyst can be prevented. |
