    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.

    Abstract: This invention relates to low volatility 5W20, 5W30, 10W40, 10W50, 15W40 or 15W50 multigrade oils for crankcase lubrication of gasoline and diesel engines, the oils comprising: a) basestock having an average basestock neutral number of not less than 105 for a 5W multigrade, not less than 145 for a 10W multigrade and not less than 200 for a 15W multigrade, b) a detergent inhibitor package including an ashless dispersant comprising an oil soluble polymeric hydrocarbon backbone having functional groups in which the hydrocarbon backbone is derived from an ethylene alpha-olefin (EAO) copolymer or alpha-olefin homo- or copolymer having an M.sub.n of from 500 to 7000, and preferably having >30% of terminal vinylidene unsaturation, and c) a viscosity modifier. These multigrade crankcase oils provide better volatility with reduced use or even without the need for expensive light neutral basestocks or non-conventional lubricant basestocks, while at the same time providing adequate control of sludge and varnish.
