LOW VOLATILITY FUNCTIONAL FLUIDS USEFUL UNDER CONDITIONS OF HIGH THERMAL STRESS AND METHODS FOR THEIR PRODUCTION AND USE

摘要

This invention relates to functional fluids incorporating base stocks and base oils that exhibit an unexpected combination of high viscosity index (130 or greater) and a ratio of measured-to-theoretical high-shear/low-temperature viscosity at -30C or lower, and the methods of making them. Specifically, the present invention relates to low-volatility/low-viscosity functional fluids comprising novel base stocks, with particular performance advantages in lubricating materials under high thermal stress, and methods to produce them.
