NN- ZINC COMPLEX INCLUDING NN-BISPYRAZOLYL BASED LIGAND CATALYST FOR POLYMERIZATION OF MONOMER HAVING A RING-TYPE ESTER GROUP AND METHOD OF FORMING POLYMER USING THE CATALYST

摘要

Zinc complex containing an N, N-bis-spiazolyl ligand, a catalyst for polymerizing a monomer having a cyclic ester group, and a method of producing a polymer using the same, the zinc complex is represented by the following formula (1).[Formula 1] In formula (1), Ar represents a cycloalkyl group, an alkoxy group or a halogen group, L represents-(CH₂)_Y-(wherein y is an integer of 1 to 5) or an arylene group, R_OneTo R₄Each independently represents hydrogen or an alkyl group, and X represents a halogen group.;
