    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.

    摘要： A catalytic process for the dimerization of norbornene and/or norbornadiene using a reduced valence state Group VIB metal oxide as the catalyst, preferably Cr(II) on a porous support such as silica. The product norbornene dimer or norbornadiene dimer is obtained in high yield and high stereospecificity at greater than 90 weight percent of the exo-trans-exo stereoisomer. The norbornene dimer is useful as a high energy density fuel. The norbornadiene dimer can be further functionalized to yield novel chemical intermediates or polymerized or copolymerized with other olefins. The norbornadiene dimer can also be hydrogenated for high energy fuel applications.
