Abstract

A method for producing a (meth)acrylic resin composition involving: a step in which a reaction product is obtained by continuously supplying a monomer mixture containing 80 to 100 mass% of methyl methacrylate and 20 to 0 mass% of alkyl ester acrylate to a tank reactor and by subjecting the monomer mixture to bulk polymerization until a polymerization inversion rate of 40 to 70 mass% is reached; a step in which the reaction product is continuously extracted and then heated to 200 to 270°C in a heater and in which unreacted monomers are separated by using an extruder having a vent; and a step in which the separated unreacted monomers are transported via an inactive gas flow and are re used as the starting material for the monomer mixture.
