METHACRYLIC RESIN PLATE FOR PRODUCING SANITARY SUPPLIES AND PROCESS FOR PRODUCING THE SAME

摘要

PURPOSE: Provided is methacrylic resin plate for producing sanitary supplies, which is excellent in peel-resistance from a glass fiber-contained unsaturated polyester resin when the plate is supported by the glass fiber-contained unsaturated polyester resin and excellent in moldability. CONSTITUTION: The methacrylic resin plate has a breaking elongation of more than 700% and a creep index of less than 1x106Pa. And the methacrylic resin plate is produced by a process comprising the steps of: mixing 5-35pts.wt. of methyl methacrylate-based polymers, 65-95pts.wt. of methyl methacrylate-based monomers, 0.1-0.5pts.wt. of the methyl methacrylate-based monomers and multi-functional monomers capable of copolymerization, and 0.01-0.30pts.wt. of a chain transfer agent containing more than 80wt% of alkyl mercaptan; adding the mixture to a cell; polymerizing the mixture; obtaining the resin plate from the cell.
