ABSTRACT:
It has now been discovered that oligomers of C.sub.6 - C.sub.20 alpha-olefins, such as 1-decene, with branch ratios below 0.19 and high viscosity indices (HVI) can be functionalized to provide unique phosphite derivatives. Functionalized polyalpha-olefin lubricants compositions are prepared with superior properties by adding functionalized organophosphites to the olefinic bond of HVI-PAO. The invention encompasses a process for the preparation of lubricant range hydrocarbons containing phosphonate functional groups, comprising;
