Abstract: L-2240-R Title: OIL-SOLUBLE REACTION PRODUCTS OF AN ACYLATED REACTION PRODUCT, A POLYAMINE, AND A MONO-FUNCTIONAL ACID 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. TECHNICAL FIELD The present invention relates to reacting polyamines and mono-functional acids with an acylating block copolymer. BACKGROUND Heretofore various solution reactions have been carried out between a polymer containing unsaturation and an anhydride. For example, U.S. Patent No. 2,524,424 to Buret relates to the treatment of rubberlike polymers from butadiene hydrocarbons with carboxylic acid anhydrides.
