摘要： The compound, [Pd(Me-DUPHOS)(MeCN).sub.2 ](BF.sub.4).sub.2, [Me-DUPHOS: 1,2-bis(2,5-dimethylphospholano)benzene] is an effective catalyst for the highly enantioselective, alternating copolymerization of olefins, such as aliphatic .alpha.-olefins, with carbon monoxide to form optically active, isotactic polymers which can serve as excellent starting materials for the synthesis of other classes of chiral polymers. For example, the complete reduction of a propylene-carbon monoxide copolymer resulted in the formation of a novel, optically active poly(1,4-alcohol). Also, the previously described catalyst is a catalyst for the novel alternating isomerization cooligomerization of 2-butene with carbon monoxide to form optically active, isotactic poly(1,5-ketone)

摘要： The present invention is a two-component catalyst system comprising (a) an alkyl magnesium (MgR2) component and (b) a Lewis acid component. The catalyst system is used for catalyzing the oligomerization and polymerization of ethylene and/or &agr;-olefins to form homopolymers and copolymers. The products range from highly linear, high molecular weight, solid polymers to highly branched, lower molecular weight oils.
