(57) [Summary] [Problem] To provide a methacrylic resin sheet for sanitary, which has excellent moldability for sanitary use and does not crack in a practical test in which contact and drying with high-temperature water are alternately repeated. To provide a stable, easy to produce method. SOLUTION: 0.5 to 3.5 parts by weight of a linear methyl methacrylate polymer having a viscosity average molecular weight of 1,000,000 or more, and a methyl methacrylate polymer 5 having a viscosity average molecular weight of 50,000 to 300,000. 25 parts by weight, methyl methacrylate-based monomer 71.5 to To 100 parts by weight of a syrup consisting of 94.5 parts by weight, 0.1 to 0.5 parts by weight of a polyfunctional monomer copolymerizable with a methyl methacrylate-based monomer and 0.01 to 0.5 parts by weight of a chain transfer agent The syrup to which 0.30 parts by weight is added is injected into a cell and polymerized to produce a methacrylic resin plate for sanitary. |
