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 thathas sufficient heat resistance. The methacrylic resin composition of the present invention is a methacrylic resincomposition for an extruded light guide panel, which is characterized in that a copolymer of methyl methacrylateand 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 chromatographyis 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/cm3 is from 60 cm3/g to 80 cm3/g.Fig. 1
