Catalyst for polymerizing aromatic vinyl compound and process for producing polymer of aromatic vinyl compound.

摘要

A catalyst for polymerizing an aromatic vinyl compound, comprising a transition metal compound as a catalyst component (A) represented by the general formula (1): where M is an element of Transition Group IV; X<1> and X<2> are respectively halogen; R<1>, R<2>, R<3>, R<4>, R<5> and R<6> 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): where n is an integer of from 4 to 60; and R<7> 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.
