Abstract

Petroleum can refine to yield lubricants and high energy fuels, such as diesel oil, gasoline and jet fuels. The petroleum stock limited, and therefore other methods have been sought. Polymers having high molecular weight find use as lubricating oil additives in three application areas of: viscosity-index improvers (VII), pour-point depressants and polymeric detergents. The present works aim to find new applications of terpolymers as viscosity-index improvers (VII) in the field of lubricants. Overwhelming utilization of natural petroleum resources may be a problem in the future. Therefore, such of higher molecular weight terpolymers can used as a VI improver (or Thickeners) and low molecular weight terpolymers can also used as synthetic base oil. The easily made vinyl esters obtained in good yield from readily available, inexpensive raw materials; also the vinyl esters are conceivably low cost monomers. The study opens up new routes of multi-functional synthetic lubricants.
