Abstract: Nitrogen-free esters of a carboxy-containing interpolymer, wherein the interpolymer has an inherent viscosity ranging from about 0.05 to 1.5 are disclosed. The esters are useful as additives in functional fluids including transmission fluids (both automatic and manual), hydraulic fluids and gear fluids. The transmission, hydraulic and gear fluids containing the esters exhibit improved shear stability while maintaining desired high and low temperature viscosity characteristics.
