CYCLOPENTAPHENANTHRENYL TITANIUM 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.
