Claims
- 1. Hydrolyzed oil soluble ene adduct of a C.sub.3 to C.sub.24 ethylenically unsaturated nitrogen-containing reactant having at least one electron withdrawing group and a copolymer of ethylene, at least one C.sub.3 to C.sub.50 alpha-monoolefin and at least one C.sub.5 to C.sub.24 non-conjugated diene, said hydrolyzed ene adduct containing carboxylate groups in molar concentration ranging up to about the molar concentration of said reactant and having a number average molecular weight of from about 1,000 to about 500,000.
- 2. An oil-soluble amide suitable as a lubricating oil sludge dispersing additive, of a hydrolyzed ene adduct of a C.sub.3 to C.sub.24 ethylenically unsaturated nitrogen-containing reactant having at least one electron withdrawing group and a copolymer of ethylene, at least one C.sub.3 to C.sub.50 alpha-monoolefin and at least one C.sub.5 to C.sub.24 non-conjugated diene, said amide containing from about 0.005 to about 0.8% by weight nitrogen and having a number average molecular weight of from about 1,000 to about 200,000.
- 3. The hydrolyzed ene adduct of claim 1, wherein said nitrogen-containing reactant is acrylonitrile.
- 4. An oil soluble amide of claim 2, wherein said C.sub.3 to C.sub.24 ethylenically unsaturated nitrogen-containing reactant is acrylonitrile; wherein said copolymer comprises about 30 to 85 mole % ethylene, about 15 to 70 mole % C.sub.3 to C.sub.8 alpha monoolefin and about 2 to 15 mole % C.sub.5 to C.sub.24 non-conjugated diene, said copolymer having a molecular weight in the range of about 10,000 to about 200,000; and wherein said amide is formed by reacting said hydrolyzed ene adduct with a C.sub.1 to C.sub.18 amine.
- 5. An oil soluble amide according to claim 4, wherein said amine is an alkylene polyamine.
- 6. A lubricating oil composition comprising a major proportion of lubricating oil and in the range of about 0.1 to 10 wt. % of the oil soluble amide of claim 4.
- 7. A lubricating oil composition comprising a major proportion of lubricating oil and in the range of about 0.1 to 10 L wt. % of the oil soluble amide of claim 5.
