Patent ID: 7399895

Claim:
A process for the preparation of oligomeric derivatives of olefin monomers, comprising contacting an olefin monomer or a mixture of olefin monomers under oligomer formation conditions with a catalyst composition to form oligomeric derivatives, wherein the catalyst composition comprises: (a) a Group 6 metal amide complex or compound, wherein the Group 6 metal amide complex corresponds to the formula M(NR 1 2 ) r X v-1 wherein, M is a Group 6 metal; R 1 independently in each occurrence is a secondary or tertiary alkyl group of from 3 to 20 carbons, a cycloalkyl group of from 5 to 20 carbons, an aryl or alkylaryl group of from 6 to 20 carbons, or a tri(C 1-20 )hydrocarbylsilyl group, and optionally two R1 groups on the same or adjacent amide groups may be joined together thereby forming a heterocycloaliphatic ring, or an alkyl-, aryl-, cycloalkyl-, or trihydrocarbylsilyl- substituted derivative thereof; X is an anionic ligand of up to 20 atoms not counting hydrogen, and optionally one or more X groups and/or one or more NR 1 2 groups may be joined together to foπn an aliphatic or aromatic ring, r is a number greater than 0 and less than or equal to v; and v is the valence of M, (b) a Group 1, 2, 12, 13 or 14 metal hydrocarbyl composition or compound, and (c) a solid support comprising aluminum phosphate, and wherein the oligomeric derivatives comprises an α-olefin product mixture of greater than 10 percent 1-octene and less than 90 percent 1-hexene, with less than 10 percent of all other α-olefin reaction products, and optionally polymer.
