STYRENE RESIN COMPOSITION AND PROCESS FOR PRODUCING THE SAME

摘要

A styrene resin composition excellent in gloss, rigidity, and surface impact strength. A solution obtained by mixing (b1) a homopolymer of a diene monomer or (b2) a styrene monomer/diene monomer copolymer having a styrene unit content of 15 wt.% or lower with (b3) a styrene monomer/diene monomer copolymer having a styrene unit content of 20 to 50 wt.%, (a1) a styrene monomer, and (a2) an alkyl (meth)acrylate is polymerized by continuous bulk polymerization in a continuous bulk polymerization line containing tubular reactors each having mixing elements fixed inside which each has no movable part.
