Abstract
A styrene resin composition excellent in luster, rigidity and surface impact strength is provided. A mixed solution of (b1) a homopolymer of a diene monomer or (b2) a copolymer of a styrene monomer and a diene monomer, the copolymer having 15% or less on a weight basis of the styrene structure units, (b3) a copolymer of a styrene monomer and a diene monomer, the copolymer having 20 to 50% on a weight basis of the styrene structure units, (a1) a styrene monomer, and (a2) a (meth)acrylic acid alkyl ester is continuously bulk polymerized in a continuous bulk polymerization line having incorporated therein a tubular reactor with a plurality of mixing elements that have no mobile part fixed inside thereof.
