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.
