(57) [Summary] [Objective] To develop a resin composition in which a styrene-based polymer or copolymer having a syndiotactic structure and a thermoplastic polymer are uniformly dispersed, and a method for efficiently producing the same. [Structure] (A) A transition metal compound component such as a titanium compound and (B) an aluminoxane, (C) a compound component that reacts with the transition metal compound to form an ionic complex, or (D) an organoaluminum compound as a main component When (co) polymerizing a styrenic monomer using a catalyst that Method for producing styrene resin composition in which thermoplastic polymer dissolved in styrene monomer or hydrocarbon solvent coexists, and styrene polymer or copolymer having syndiotactic structure and thermoplastic polymer Is a resin composition in which is uniformly dispersed. |
