ABSTRACT:
Novel polymers comprising polyolefin-substituted amines grafted with aromatic N-containing monomers such as aniline, have been found to provide oil soluble polymers having dispersant and antioxidant properties in oleaginous compositions, including fuel and lubricating oils. The polymers of this invention are further useful in electrical applications. These materials are formed by a process which comprises: (a) contacting an amine compound having at least two reactive nitrogen moieties with at least one long chain hydrocarbon-substituted reactant in an amount and under conditions sufficient to form a N-containing polymer adduct containing reactive amine groups, and (b) contacting the N-containing polymer adduct with at least one aromatic N-containing monomer under polymerization conditions to graft said N-containing polymer adduct with aromatic N-containing polymer segments. The long chain hydrocarbon-substituted reactant can comprise materials such as (i) long chain hydrocarbons substituted with mono- or dicarboxylic acid, anhydride or ester groups; (ii) halogenated long chain hydrocarbons; (iii) mixtures of formaldehyde and a long chain hydrocarbyl substituted phenol; and (iv) mixtures of formaldehyde and a reaction product formed by reaction of long chain hydrocarbons substituted with mono- or dicarboxylic acid, anhydride or ester groups and an amino-substituted, optionally hydrocarbyl-substituted phenol.
