摘要： A method of producing a (meth)acrylic resin composition. The method comprises a step of continuously feeding a monomer mixture comprising 80 to 100% by mass of methyl methacrylate and 20 to 0% by mass of an alkyl acrylate to a tank reactor and bulk polymerizing the monomer mixture until obtaining a polymerization conversion of 40 to 70% by mass to prepare a reaction product; continuously discharging the reaction product, and heating the reaction product to 200° C. to 270° C. with a heater, and then separating the unreacted monomer with a extruder equipped with a vent; and transferring the separated unreacted monomer entrained by an inert gas flow to reuse the separated unreacted monomer as a raw material of the monomer mixture.
