摘要:The present invention is a two-component catalyst system comprising (a) an alkyl magnesium (MgR 2 ) component and (b) a Lewis acid component. The catalyst system is used for catalyzing the oligomerization and polymerization of ethylene and/or α-olefins to form homopolymers and copolymers. The products range from highly linear, high molecular weight, solid polymers to highly branched, lower molecular weight oils.

摘要:The present invention relates to butadiene rubber polymers having low molecular weights and narrower molecular weight distributions than those known in the art. The present invention also relates to a metal-containing catalyst system, a solution polymerization process for the manufacture of said butadiene rubber, a one-pot process for the synthesis of the hydrogenated diene polymers, and a process for the hydrogenation of diene polymers.
