CATALYST COMPOSITION AND ITS PREPARATION, AND USE FOR PREPARING POLYMER FROM ETHYLENIC UNSATURATED MONOMER

摘要

PROBLEM TO BE SOLVED: To provide a catalyst composition and its preparation method and a use of the catalyst composition for preparing a polymer from an ethylenic unsaturated monomer.

SOLUTION: The catalyst composition contains a pair of cationic metal complexes containing at least one metallic pair, i.e., a complex of a specific structure that a first metal selected from Cu, Fe, Co, Ru, Rh, Cr and Mn and a second metal selected from Ni, Pd, Cu, Fe, Co, Rh, Cr and Mn have an interneclear distance of 1.5-20 Å. The polymerization method for the polar and/or the non-polar ethylenic unsaturated monomer using the catalyst composition and an addition polymer manufactured thereby are provided.
