Abstract

An aim of the invention is 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. The 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] and an alkoxy silicon compound (B) represented by formula [2] Ar3-Si(OR1)aR2 3-a 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.

Description

technical field [0001] The present invention relates to a polymeric resin composition containing a reactive organosilicon compound, in particular, to a polymer resin composition capable of forming a resin having excellent optical characteristics (high refractive index, low Abbe number), high heat resistance (heat yellowing resistance, crack resistance) properties) cured polymeric composition. Background technique [0002] Plastic lenses are used in mobile phone cameras, digital cameras, vehicle-mounted cameras, etc., and are required to have excellent optical characteristics corresponding to the purpose of the device. In addition, in accordance with the state of use, high durability such as heat resistance, weather resistance, etc., and high productivity that can be molded with good yield are required. [0003] In recent years, for the purpose of reducing installation costs, a method of collectively mounting camera modules by solder reflow has been proposed. As the plastic ...
