POLYMERIZABLE RESIN COMPOSITION COMPRISING REACTIVE SILICONE COMPOUND

摘要

[Problem] To provide a polymerizable composition ideal for producing moldings, which maintain a high refractive index and low Abbe number and can limit discoloration (heat-induced yellowing) and cracks that occur as a result of a high-temperature thermal history. [Solution] A polymerizable composition comprising (a) 100 parts by mass of a reactive silicone compound obtained by polycondensation of a polycondensing compound comprising at least a diaryl silicate compound (A) represented by formula [1] [1] and an alkoxy silicon compound (B) represented by formula [2] Ar3-Si(OR1)aR2 3-a [2] in the presence of an acid or a base, (b)1-200 parts by mass of a (meth)acrylate compound, and (c) 0.1-50 parts by mass of a polymer with a weight average molecular weight of 5,000-100,000.
