Transition metal complex catalyst composition for polymerization of monomer having cyclic ester group and method of producing polymer using the same

Abstract

The present invention relates to a transition metal complex catalyst composition for polymerization of a monomer having a cyclic ester group and a method of producing a polymer using the same. More particularly, the invention provides a catalyst composition comprising a transition metal complex containing aminopyridine and aminoquinoline ligands, and a method of producing a polymer having high heterotacticity with high conversion rate even at room temperature by using the same. Since the catalyst composition for polymerization of a monomer having a cyclic ester group according to the invention comprises a transition metal compound that is chemically stable in air, it is capable of effectively producing a polymer having high heterotacticity (Pr) with high conversion rate at room temperature or below room temperature without satisfying high-temperature conditions.
