Functionalized polymer composition for grease

摘要

A grease composition containing a polymer with (a) monomers (i) at least one unsaturated alpha,beta-carboxylic acid ester containing an alkyl group with about 10 to about 20 carbon atoms; and (ii) at least one unsaturated alpha,beta-carboxylic acid ester containing an alkyl group with about 4 to about 11 carbon atoms different from monomer (i); and (iii) at least one unsaturated dicarboxylic acid anhydride or derivatives thereof; and (iv) optionally at least one unsaturated alpha,beta-carboxylic acid ester containing an alkyl group with about 1 to about 3 carbon atoms; and optionally (b) at least one non-monomeric amine with primary functionality, secondary functionality or mixtures thereof; and optionally (c) other performance additives; and (d) at least one thickening agent, and (e) an oil of lubricating viscosity. The invention further relates to the process to make the composition and its use in greases.
