Oil-soluble reaction products of an acylated reaction product, a
polyamine, and mono-functional acid
摘要:
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.
