摘要： A polyalphaolefin polymer, having a kinematic viscosity at 100° C. of 135 cSt or greater, is shear stable. The polymer either has not more than 0.5 wt % of the polymer having a molecular weight of greater than 60,000 Daltons, or after being subjected to twenty hours of taper roller bearing testing, the polymer has a kinematic viscosity loss of less than 9%. Such a shear stable polyalphaolefin is obtained by either mechanical breakdown of a high viscosity polyalphaolefin or by a selective catalyst system used in oligomerization or polymerization of the feedstock.

摘要： Disclosed is a lubricant base stock blend comprising a PAO base stock and an alkylated aromatics (AA) base stock, wherein at least the longer portion of the pendant groups attached to the carbon backbones of the PAO molecules have comparable length to at least the longer portion of the side chain groups attached to the aromatic ring structure of the AA molecules. The comparable lengths of at least the longer portion of the pendant groups and the side chain groups lead to enhanced improvement in oxidation stability of the blend.
