Abstract

Provided is a method for manufacturing a methacrylic resin composition having excellent surface processability and displaying excellent preservability of formed surface processing. A method for manufacturing a methacrylic resin composition, wherein the methacrylic resin composition comprises two or more types of methacrylic resins that each have a structural unit (X) having the same type of cyclic structure-containing main chain, the methacrylic resin composition has a Vicat softening temperature of 120° C. to 160° C., methanol-soluble content is contained in an amount of 5 mass % or less relative to 100 mass %, in total, of the methanol-soluble content and methanol-insoluble content, comprising mixing a low molecular weight component and a high molecular weight component.
