Abstract

There are disclosed a catalyst for producing an aromatic vinyl compound-based polymer composition which catalyst comprises (A) at least two different transition metal compounds each having one .pi.-ligand and (B) an ionic compound comprising a noncoordinate anion and a cation and/or an aluminoxane, and (C) a Lewis acid to be used as the case may be; and a process for producing an aromatic vinyl compound-based polymer composition having a high degree of syndiotactic configuration in its aromatic vinyl chains which process comprises polymerizing an (a) aromatic vinyl compound and (b) an olefinic compound and/or a diolefinic compound in the presence of the above catalyst. The catalyst according to the present invention, which has a high activity, can afford an resin composition comprising an aromatic vinyl compound-based polymer having a syndiotactic configuration and a rubbery elastomer, each being uniformly mixed therein, and thus the resin composition can efficiently be produced by the use of the above catalyst.
