The present invention provides a polymerizable composition suitable for producing a molding that maintains a high refractive index and a low Abbe's number, discoloration (thermal yellowing) resulting from high thermal hysteresis can be reduced, no Tg and a low CTE are exhibited, and has good mold release properties. A polymerizable composition comprising: 100 parts by mass of a reactive silicone compound (a) obtained by polycondensation, in the presence of an acid or a base, of a polycondensable compound containing at least a diarylsilicic acid compound A, an alkoxy silicon compound B having a phenyl group or a naphthyl group having at least one group having a polymerizable double bond, and an alkoxy silicon compound C containing a fluoro group; and 1 part by mass to 200 parts by mass of a (meth) acrylate compound (b), and a cured product and a material for high refractive index resin lens which are obtained from the polymerizable composition. |
