ABSTRACT:
A styrene type monomer is polymerized by use of a catalyst consisting of (a) a transition metal compound, (b1) a compound capable of forming an ionic compound by reacting with the transition metal compound, and if necessary (d) an alkylating agent, which comprises subjecting to a polymerization reaction a monomer to which (c) an oxygen-containing compound having a branched alkyl group, or (c) said oxygen-containing compound and (d) all or a part of an alkylating agent have previously been added, or by a process for producing a polymer in which a monomer particularly a styrene type monomer is polymerized by use of a catalyst consisting of (a) a transition metal compound, (b1) a compound capable of forming an ionic compound by reacting with the transition metal compound, (b2) a specific oxygen-containing compound, and if necessary (d) an alkylating agent, which comprises subjecting to a polymerization reaction a monomer to which (c) an oxygen-containing compound having a branched alkyl group, or (c) said oxygen-containing compound and (d) all or a part of an alkylating agent have previously been added.
