    • The present invention relates to a process for efficiently producing an aromatic vinyl compound-based copolymer having a high degree of syndiotactic configuration in its aromatic vinyl chain by copolymerizing an aromatic vinyl compound with an olefin, etc. in the presence of a catalyst comprising (A) a transition metal compound, (B) an ionic compound comprising a non-coordinate anion and a cation of a typical metal belonging to the group 4 and (C) a Lewis acid to be used as the case may be. It is made possible by the use of the highly active catalyst according to the above process to efficiently produce an aromatic vinyl compound-based copolymer which is minimized in residual amounts of ash and toxic substances a high degree of syndiotactic configuration in its aromatic vinyl chain, while dispensing with an expensive aluminoxane.
