Methacrylic resin composition for extruded light guide panel and light guide panel made thereof

摘要

A methacrylic resin composition is provided which is suitable for producing an extruded light guide panel that has sufficient heat resistance. The methacrylic resin composition of the present invention is a methacrylic resin composition for an extruded light guide panel, which is characterized in that a copolymer of methyl methacrylate and an acrylic acid ester is contained, and a ratio of methyl methacrylate unit in the copolymer which ratio is determined by an analysis with pyrolysis gas chromatography is 96% by weight or more, and a reduced viscosity determined at 25 °C as a chloroform solution of the composition with a concentration of 0.01 g/cm 3 is from 60 cm 3 /g to 80 cm 3 /g.
