Meth) method for producing the acrylic resin composition

Methyl methacrylate, a chain transfer agent and a radical polymerization initiator always contain, optionally contain an acrylic acid alkyl ester, and the raw material weight ratio of alkyl acrylate / methyl methacrylate is 0/100 to 20/80 solution was continuously fed to the tank reactor and to bulk polymerization at a polymerization conversion of 40 to 70% by weight cistern type reactor to obtain a reaction product, and the reaction product from the tank reactor continuously extracted, the reaction product withdrawn and heated in a heat exchanger, the volatiles were removed from the heated reaction product, a liquid additive strainer with filter and then removal of volatiles was carried out by a method having the step of adding a liquid additive that is strained to the reaction product to obtain a (meth) acrylic resin composition.
