Abstract:
Provided are a methacrylic resin having high heat resistance, highly controlled birefringence, and excellent color tone and transparency, and a production method, a molded article, and an optical or automotive component of the methacrylic resin. The methacrylic resin includes N-substituted maleimide monomer-derived structural units (B) in a main chain thereof in a proportion of 5 mass % to 40 mass %. The N-substituted maleimide monomer-derived structural units (B) include a structural unit represented by formula (1). The methacrylic resin has a glass transition temperature of higher than 120° C. and not higher than 160° C. The content of components that exhibit light absorption at a wavelength of 400 nm in methanol-soluble content of the methacrylic resin is more than 0 mass % and not more than 2 mass % as calculated in terms of N-phenylmaleimide.

Claim (Index 3):
The methacrylic resin according to  claim 1 , further comprising, in the main chain thereof, methacrylic acid ester monomer units (A) in a proportion of 50 mass % to 95 mass % and other vinyl monomer units (C) that are copolymerizable with a methacrylic acid ester monomer in a proportion of 0 mass % to 20 mass % relative to 100 mass % of the methacrylic resin.
