Title: SYNTHETIC POLYOLEFIN LUBRICANT BLENDS HAVING HIGH VISCOSITY INDICES
Abstract:
A lubricant mixture having enhanced viscosity index comprising: a) a low viscosity C20-C60 lubricant range liquid comprising substantially linear hydrocarbons prepared by shape selective catalysis of a lower olefin with a medium pore acid zeolite catalyst to provide substantially linear liquid olefinic intermediates or C20 hydrogenated lubricants, the lubricant range liquid having a kinematic viscosity of 2-10mm2/s at 100°C; and b) at least one poly(alpha-olefin) having a viscosity of greater than 20mm2/s and viscosity index improvement properties.
