A QUASI-LIVING METAL CATALYST FOR ETHYLENE HOMO-POLYMERIZATION AND CO-POLYMERIZATION WITH 5-NORBORNEN-2-YL ACETATE

摘要

Methods and compositions for the generation of quasi-living catalysts for homo-polymerization of olefins such as ethylene, alpha-olefins and functionalized olefins for the co-polymerization of olefins with functionalized monomers is disclosed. A process for producing these homo- and co-polymers is also disclosed. A polymeric material with enhanced hydrophilic properties, generated by the co-polymerization of ethylene with 5-norbornen-2-yl acetate, is also disclosed. The initiator compound used is exemplified by a combination of two neutral metal complexes (group VIII of the periodic table), namely Ni (cyclooctadienne)2 and a bidentate complex (e.g. L(iPr2) Ni (CH2Ph) (PMe3) where L is N-(2,6-diisopropylphenyl)-2-(2,6-diisopropylphenylimino)propanamide).
