METHOD FOR PREPARING OLEFIN-DIENE COPOLYMER USING TRANSITION METAL COMPOUND INCLUDING THIOPHENE-CONDENSED RING CYCLOPENTADIENYL LIGAND

摘要

The present invention relates to a preparation method for olefin-diene copolymer that comprises polymerizing at least one olefin-based monomer and at least one diene-based monomer in the presence of a catalyst comprising a novel transition metal compound. Using the novel transition metal compound as a catalyst, the preparation method for olefin-diene copolymer according to the present invention can not only acquire high catalytic activity for copolymerization of the olefin and diene monomers to achieve high process efficiency but allow it to easily control the fine-structure characteristics of the copolymer, thereby providing an olefin-diene copolymer having desired properties with ease.
