| titleOfInvention | Alpha-olefin polymerization catalyst and process |
| abstract | Process for modifying a titanium trichloride-organoaluminum alpha-olefin polymerization catalyst to reduce production of alkane soluble products during polymerization of alpha-olefins in the presence of such catalyst without substantial decreases in catalyst activity, said process comprising combining in an inert diluent and in the substantial absence of catalyst poisons, components comprising an alkylaluminum component, a titanium trichloride, hydrogen sulfide or a bis-(trialkyltin)sulfide, a tertiary amine, and an aromatic dicarbonyl compound selected from the group consisting of dialdehydes and lower alkyl diesters of ortho-, para- and meta-phthalic acids. Polyalpha-olefins containing reduced levels of low molecular weight and amorphous components are produced by contacting the catalysts with at least one polymerizable alpha-olefin under polymerizing conditions. |
