摘要： The present invention discloses an optical material having excellent transparency, impact resistance and heat resistance and having a low specific gravity and a high refractive index comprising a resin obtained by radical polymerization of specific difunctional (meth)acrylate (A) and aromatic vinyl monomer (B) and, if necessary, polymerizable monomer (C) copolymerizable with the ingredients (A), or (B) or by radical polymerization of the ingredients (A), (B) and (C) under the presence of a radical polymerizable or not-radical polymerizable compound having alkoxysilyl group, epoxy group, alcoholic hydroxy group or carboxyl group in the molecule, an optical molding product comprising the optical material, as well as production process therefor. The optical molding product is utilized as for ophthalmic lenses or lenses for various kinds of optical equipments, prisms, optical fibers, optical waveguides and optical discs.
