CYCLOPENTAPHENANTHRENEYL METAL COMPLEXES AND POLYMERIZATION PROCESS |
摘要 |
Group 4 metal complexes comprising a cyclopentaphenanthreneyl ligand, catalytic derivatives thereof and their use as olefin polymerization catalysts, especially for the copolymerization of ethylene and a vinylaromatic monomer are disclosed. The resulting copolymers are uniform, pseudo-random copolymers of ethylene and a vinylaromatic monomer having a cluster index, CIES less than 1.0 and a polymerized vinylaromatic monomer content less than 50 mole percent.
