Abstract:
A method for producing styrenic polymers, which comprises:polymerizing styrenes in the presence of a polymerization catalyst, which comprises: (A) a transition metal compound, (B) an oxygen-containing compound and/or a compound capable of reacting with a transition metal compound to form an ionic complex, (C) a compound which is a reaction product of <1> at least one compound selected from the group of compounds consisting of formulae (R1)3â€”Câ€”R3, R4â€”COâ€”R5 and R6â€”COâ€”R7, and <2> a compound of formula, Al(R2)3: in which R1 is a halogen atom, an aliphatic hydrocarbon group having from 1 to 30 carbon atoms, an aromatic hydrocarbon group having from 6 to 30 carbon atoms, an alkoxy group having from 1 to 30 carbon atoms, an aryloxy group having from 6 to 30 carbon atoms, a thioalkoxy group having from 1 to 30 carbon atoms, or a thioaryloxy group having from 6 to 30 carbon atoms; R3 is hydroxyl, an alkoxy group having from 1 to 30 carbon atoms, an aryloxy group having from 6 to 30 carbon atoms, a thioalkoxy group having from 1 to 30 carbon atoms, or a thioaryloxy group having from 6 to 30 carbon atoms; R4 and R5 each represents hydrogen, halogen, an aliphatic hydrocarbon group having from 1 to 30 carbon atoms or an aromatic hydrocarbon group having from 6 to 30 carbon atoms, R6 is a hydrogen atom, an aliphatic hydrocarbon group having from 1 to 30 carbon atoms, an aromatic hydrocarbon group having from 6 to 30 carbon atoms, an alkoxy group having from 1 to 30 carbon atoms, an aryloxy group having from 6 to 30 carbon atoms, a thioalkoxy group having from 1 to 30 carbon atoms, or a thioaryloxy group having from 6 to 30 carbon atoms or an amino group; and R7 is hydroxy, an alkoxy group having from 1 to 30 carbon atoms, an aryloxy group having from 6 to 30 carbon atoms, a thioalkoxy group having from 1 to 30 carbon atoms, or a thioaryloxy group having from 6 to 30 carbon atoms; or an amino group; and R1, and R3 or R4 and R5 or R6 and R7 may be optionally bonded to each other to form a cyclic structure; and R2 represents a hydrocarbon group; and optionally, (D) an alkylating agent.
