A catalyst for polymerizing an aromatic vinyl compound, comprising a transition metal compound as a catalyst component (A) represented by the general formula (1):n n where M is an element of Transition Group IV; X¹ and X² are respectively halogen; R¹, R², R³, R⁴, R⁵ and R⁶ are respectively hydrogen or an alkyl group of from 1 to 6 carbon atoms; and m is an integer of 1 to 6; and an aluminoxane as a catalyst component (B) represented by the general formula (2) or (3):n n where n is an integer of from 4 to 60; and R⁷ is an alkyl of from 1 to 6 carbon atoms, phenyl or benzyl, preferably methyl, and a process for producing a polymer of an aromatic vinyl compound, comprising polymerizing the aromatic vinyl compound in the presence of the catalyst. |
