    摘要： A process for the production of hydrocarbon lubricant basestock comprises contacting C.sub.2 to C.sub.20 alpha-olefin feedstock, or mixtures thereof, e.g., 1-decene, under heterogeneous oligomerization conditions with a catalyst comprising halides of a metal component anchored on an adsorbent inorganic oxide solid, e.g., silica, by an oxygen-metal bond to provide a reaction mixture containing said hydrocarbon lubricant basestock. The catalyst is prepared by contacting the inorganic oxide solid with organic metal halide of the formula RMXY wherein R is alkyl or aryl, M is aluminum, X is halogen and Y is selected from the group consisting of halogen, alkyl, alkenyl, aryl, alkoxy, and amido moieties.

    摘要： A catalyst composition for polymerizing alpha-olefins is prepared by treating a carrier containing OH groups with a liquid solution containing an excess of an organomagnesium composition with respect to the OH groups and contacting the thus-formed magnesium-containing carrier with a hydrocarbyl alcohol and at least one transition metal compound. Prior to contacting the magnesium-containing carrier with the alcohol, most of the liquid must be removed therefrom, so that it comprises not more than about 6% of the liquid. The amount of the transition metal compound is such that the molar ratio thereof to magnesium in the reaction mixture is about 0.3 to about 0.9. Also disclosed is a process for polymerizing alpha-olefins in the presence of the catalyst of the invention.
