<p>Disclosed is a methacrylic resin monomer composition comprising at least any of the following (A) to (C): (A) a methyl methacrylate monomer and/or a syrup thereof; (B) a compound represented by the general formula (1); and (C) a radical initiator,
wherein, in the formula, R 1 and R 3 , and R 2 and R 4 represent hydrogen atoms or methyl groups at the same, respectively. This composition enables to obtain a crosslinkable methacrylic resin which is improved in resin properties such as heat resistance, rigidity, low water absorption, chemical resistance and the like without deteriorating high transparency a PMMA originally has. A transparent member and an optical member composed of such a resin are also disclosed.</p> |
