| titleOfInvention | Methacrylic resin composition, molded body, and optical member |
| abstract | To provide a methacrylic resin composition having high heat resistance, highly controlled birefringence, high heat resistance, highly controlled birefringence, and excellent light transmittance, color tone, transparency and injection moldability. It is. A methacrylic resin containing at least a structural unit derived from an N-substituted maleimide monomer in the main chain, a glass transition temperature of over 120 ° C. and 160 ° C., a resin temperature of 270 ° C. and a shear rate of 1000 sec −1 . A solution having a melt viscosity of 250 pa · sec or less and an absolute value of a photoelastic coefficient of 1 × 10 −12 pa −1 or less and having the resin composition dissolved in chloroform at a volume percentage of 20% by mass, The light transmittance measured at 100 mm at a wavelength of 470 nm is 94% or more, the light transmittance measured at a wavelength of 700 nm is 96% or more, and a predetermined fatty acid ester and a trivalent phosphorus element A methacrylic resin composition comprising a phosphorus-based antioxidant having a predetermined melting point.
