LIGHT-DIFFUSING METHACRYLIC RESIN COMPOSITION AND MOLDED PRODUCT THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a light-diffusing methacrylic resin composition which hardly undergoes whitening when subjected to hot stretching molding and can maintain a good light transmission property after molded, and a molded product comprising the light-diffusing methacrylic resin composition. SOLUTION: The light-diffusing methacrylic resin composition comprises 100 pts. mass of a methacrylic resin and 0.5-10 pts. mass of a crosslinked siloxane-based resin particle, where the crosslinked siloxane-based resin particle has an average particle size of 1-10μm and the mass reduction ratio at 250 deg.C as measured by the thermogravimetry(TG) of the crosslinked siloxane-based resin particle is not higher than 1%. The molded product comprises the light- diffusing methacrylic resin composition.
