There is disclosed a process for efficiently producing a styrenic copolymer comprising a styrenic monomer and a monomer containing a polar group an internally olefic monomer by the use of a specific highly active catalyst. Specifically the present invention provides a process for producing a styrenic copolymer which comprise copolymerizing (a) styrenic monomer and (b) a monomer containing a polar group or an internally olefinic monomer in the presence of a catalyst comprising as primary ingredients (A) a transition metal compound and (B) a coordination complex compound comprising a cation and an anion in which a plurality of radicals are bonded to a metal and optionally (C) an organoaluminum compound. The styrenic copolymer thus obtained forms a resin excellent in heat resistance and mechanical strength and finds effective use as a raw material of a variety of molded products.
