Title:
METHACRYLIC RESIN COMPOSITION AND PRODUCTION METHOD THEREOF, AND RESIN MOLDING
Document Type and Number:
Japanese Patent JP2015074740
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a methacrylic resin composition having fire resistance and excellent in heat resistance, and to provide a resin molding obtained from the methacrylic resin composition.SOLUTION: There is provided the methacrylic resin composition according to one embodiment, which is obtained by polymerizing a polymerizable composition (x) containing a monomer composition (a) of 100 pts.mass, phosphoric acid ester (B) of 9.3 to 11.8 pts.mass and an antioxidant (C) of 0.005 to 0.6 pts.mass, the monomer composition (a) containing MMA (methyl methacrylate)-based monofunctional monomer (a-1) of 99.6 to 99.9 mass% and polyfunctional monomer (a-2) of 0.1 to 0.4 mass%. There is provided the methacrylic resin composition according to another embodiment, which is obtained by polymerizing a polymerizable composition (x') containing a monomer composition (a') of 100 pts.mass, phosphoric acid ester (B) of 9.3 to 11.8 pts.mass and the antioxidant (C) of 0.005 to 0.6 pts.mass, the monomer composition (a') containing a MMA-based polymer (A-1) of 1 to 30 mass%, a MMA-based monofunctional monomer (a-1) of 69.6 to 98.9 mass% and a polyfunctional monomer (a-2) of 0.1 to 0.4 mass%.
