ANTIWEAR/ANTIOXIDANT ADDITIVES BASED ON DIMERCAPTO DERIVATIVES OF ACRYLATES AND METHACRYLATES POLYMERS AND AMINE REACTION PRODUCTS THEREOF

摘要

The invention relates to zinc and phosphorus free additives for lubricating compositions which are produced by a free radical reaction between a dimercaptothiadiazole and monomer oligomer or homologue of acrylates or methacrylate, which in minor amounts impart antiwear/extreme pressure and antioxidation properties to the lubricant.
