Abstract:
Disclosed is a methacrylic resin monomer composition at least containing all of the following (A)-(C): (A) a methyl methacrylate monomer and/or a syrup thereof; (B) a compound represented by the general formula (1): (wherein R1 and R3, and R2 and R4 independently represent hydrogen atoms or methyl groups); and (C) a radical initiator. This composition enables to obtain a crosslinkable methacrylic resin which is improved in resin properties such as heat resistance, rigidity, low water absorbency and chemical resistance without deteriorating high transparency a PMMA originally has.
