Abstract
A process for producing a novel-highly active lanthanide containing catalyst comprising the product formed by admixing a lanthanide hydroxyhalide and an electron donor bidentate organic ligand chosen from among diamines, dihydric alcohols, and diketones with an organoaluminum cocatalyst component and its use in the polymerization of olefins, especially olefins such as ethylene and 1,3-butadiene.
Claims8
A process for the polymerization of olefins which comprises contacting at least one olefin under polymerization conditions with a catalyst composition comprising a component A formed by admixing a rare earth metal hydroxyhalide and an electron donor bidentate organic ligand having from 2 to about 20 carbon atoms selected from among diamines, dihydric alcohols, and diketones, and a component B comprising an organoaluminum compound.
