    摘要： A simple process for producing acrylic resins excellent in toughness was provided. The process comprises putting a monomer mixture comprising (i) 80 to 99 parts by weight of a methacrylic monomer containing 50% by weight or more of methyl methacrylate and (ii) 1 to 20 parts by weight of a diene-based rubber, in contact with a radical polymerization initiator, then pouring them in a mold and polymerizing the mixture.
