| titleOfInvention | Process for the oligomerization of .alpha.-olefins having low unsaturation, the resulting polymers, and lubricants containing same |
| abstract | A process for the preparation of a poly(.alpha.-olefin) copolymer is disclosed wherein the process comprises polymerizing at least one .alpha.-olefin, preferably 1-decene, and at least one bulky olefin, preferably norbornene, in the presence of hydrogen and a catalytically effective amount of catalyst comprising the product obtained by combining a metallocene procatalyst with a cocatalyst, the metallocene procatalyst being at least one compound of general formula: (CP1R1m)R3(Cp2R2p)MXq wherein Cp1 of ligand (Cp1R1m) and Cp2 of ligand (Cp2R2p) are the same or different cyclopentadienyl rings, R1 and R2 each is, independently, hydrogen or a hydrocarbyl, halocarbyl, heterocarbyl, hydrocarbyl-substituted organometalloid or halocarbyl-substituted organometalloid group containing up to about 20 carbon atoms, m is 0 to 5, p is 0 to 5 and two R1 and/or R2 substituents on adjacent carbon atoms of the cyclopentadienyl ring associated therewith can be joined together to form a ring containing from 4 to about 20 carbon atoms, R3 is a bridging group bridging Cp1 with Cp2, M is a transition metal having a valence of from 3 to 6, each X is a non-cyclopentadienyl ligand and is, independently, halogen or a hydrocarbyl, oxyhydrocarbyl, halocarbyl, hydrocarbyl-substituted organometalloid, oxyhydrocarbyl-substituted organometalloid or halocarbyl-substituted organometalloid group containing up to about 20 carbon atoms, and q is equal to the valence of M minus 2, the cocatalyst being an aluminoxane and it being provided that ligand (Cp1R1m) is different that ligand (Cp2R2p) and bridging group R3 contains at least two bulky groups. |
