Abstract: A compsn. comprising: (a) oil-soluble, olefin-based polymer(s); (b) oil-soluble polymer(s) having N functionality, (a) and (b) combined in a liq. nonpolar oleophilic medium exhibit incompatibility evidenced by phase separation; (c) sufficient hydrocarbyl substd. hydroxyaromatic material(s) contg. at least 24C to reduce the incompatibility of (a) and (b); and (d) a liq. nonpolar oleophilic medium. Also claimed are (1) A lubricant prepd. by mixing the above compsn., (d) being present in a concentrate-forming amt., with an oil of lubricating viscosity. (2) Improving the mutual compatibility of (a) and (b) comprising combining with a mixt. of (a) and (b) in a liq. nonpolar oleophilic medium sufficient hydrocarbyl substd. hydroxyaromatic material contg. at least 24C.

Abstract: Oil-soluble compositions, useful as dispersant viscosity modifiers, are formed by the reaction product of an acylating product (D) a (F) polyamine, and a (G) mono-functional acid. The compositions can be prepared in solvent such as a hydrocarbon oil or in the absence of a solvent.
