ABSTRACT:
Esters made from (A) high molecular weight carboxylic acid reagents derived from low molecular weight ethylenically unsaturated carboxylic acid reagents and oxidized ethylene-propylene interpolymers and (B) mono- or polyhydric alcohols are useful in lubricant compositions and normally liquid fuel compositions as viscosity improving agents and sludge dispersants. Esters wherein the low molecular weight reagent is maleic anhydride and the alcohol is a polyol such as pentaerythritol are particularly useful.
