ABSTRACT:
This invention relates to a novel class of Dimer Alkyl Silicone Polymers (DASP) and their use to reduce surface tension of lubrication oil. The improved lubricant composition based upon a very specific class of dimer alkyl silicone polymers (DASP) that despite their solubility in oil lower surface tension and improve lubrication when added at low concentrations to lubricating oils.
