Abstract: NONCORROSIVE AND LOW-SLUDGING EP ADDITIVES FOR LUBRICATING OILS TO IMPROVE THE LOAD-CARRYING ABILITY OF SYNTHETIC ESTER LUBRICANTS ARE PROVIDED. THE ADDITIVE COMPOSITIONS OF THIS INVENTION ARE ACID-TERMINATED HYDROXY ESTER COMPOUNDS OBTAINED BY THE PARTIAL ESTERIFICATION OF A POLYBASIC ACID WITH A GLYCIDYL ESTER. THE EXTREME PRESSURE PROPERTIES OF SYNTHETIC ESTER LUBRICATING OIL COMPOSITIONS ARE SIGNIFICANTLY INCREASED BY INCORPORATING A SMALL AMOUNT OF COMPOUNDS SUCH AS HALF-ESTERS DERIVED FROM THE REACTION OF DIMER ACID AND A GLYCIDYL ESTER OF A BRANCHED-CHAIN ACID.
