  • Process for the oligomerization of ?-olefins having low unsaturation, the resulting polymers, and lubricants containing same
    Patent number: 7037974
    Abstract: A poly(?-olefin) copolymer obtained from the polymerization of at least one ?-olefin having from 2 to about 20 carbon atoms and at least one bulky olefin, the process comprising polymerizing the monomers in the presence of hydrogen and a catalytically effective amount of a catalyst comprising the product obtained by combining a metallocene procatalyst with a cocatalyst; lubricant compositions comprising such poly(?-olefin) copolymer; and a method for improving the viscosity index of a lubricant composition using such poly(?-olefin) copolymer.
    Type: Grant
