Abstract: This invention relates to an oligomerization catalyst comprising a zirconocene and one or more alkyl aluminoxanes wherein the alkyl is selected from methyl, ethyl and mixtures thereof and the ratio of equivalents of methyl to ethyl in the product ranges from about 4 to about 0.25 and wherein the atom ratio of aluminum to zirconium ranges from about 1 to about 100. It further relates to the method for preparing the catalyst and the use of the catalyst in an oligomerization process. The catalyst is particularly suited for the oligomerization of ethylene.

Abstract: This invention relates to a process for preparing aluminoxines from trialkyl aluminum compounds and an water dispersion produced using a high speed, high shear-inducing impeller.

Abstract: This invention relates to a process for preparing aluminoxanes from trialkyl aluminum compounds and an ultrasonically produced water dispersion.

Abstract: Zirconocene/aluminoxane polymerization/oligomerization catalysts are stabilized against aging prior to use as catalysts by use of at least 1 mole of 3,3,3-trialkyl-1-propene per mole of metallocene.

Abstract: This invention relates to a process for dimerizing an alpha olefin to a vinylidene olefin which comprises contacting said alpha olefin with a catalyst comprising (a) cyclo(pentadienyl)zirconium or hafnium metallocene and (b) an aluminoxane wherein the atom ratio of Al to Zr or Hf in the catalyst ranges from about 1 to about 100.

Abstract: This invention relates to alumina and/or silica supported catalysts which have a portion of their pores in the range of 75-1500 .ANG. and wherein are or more catalytically active metal species is contained substantially within said pores. Carbon black particles having pores of 75-1500 .ANG. and which have been reacted with the catalyst metal are used to prepare the catalyst using alumina and/or silica gels.
