Patent

CA 2321765

Novel catalyst systems which comprise pyridine-2-carboxaldimine nickel complexes can be used with methylaluminoxane in slurry polymerization processes to polymerize mono-1-olefins and, optionally a higher alpha-olefin comonomer, to produce low molecular weight polymers.

L'invention concerne de nouveaux systèmes de catalyseurs comprenant des complexes de nickel-pyridine-2-carboxaldimine qui peuvent être utilisés avec le méthyle-aluminoxane dans des procédés de polymérisation en suspension, de manière à polymériser des mono-1-oléfines et, éventuellement un comonomère d'alpha-oléfine, afin de produire des polymères de faible poids moléculaire.
