权利要求: What is claimed is:1. A lubricant composition comprising a major amount of a mineral lubricating oil and a dispersant amount of an oil-soluble, nitrogen-containing reaction product prepared by first reacting at least one ethylenically unsaturated aliphatic dicarboxylic acid acylating agent of the formulaadditional double bond so that there ethylenically unsaturated bond in the group joiningwherein each R' is independently hydrogen or an aliphatic hydrocarbon radical where at least one R' variable contains at least one ethylenic bond or a pair of R' variables on the same or adjacent carbon atoms together form an is at least one hydrocarbylene and carbon containing at least fifty aliphatic carbon atoms in an equivalent ratio of (A) to (B) of 1:0.5 to about 1:3 at a temperature of about 50° C. to about 350° C. to form the first reaction product and subsequently reacting said first reaction product with (C) at least one amine having at least one primary or secondary amino group present therein at a temperature of about 50° C. to about 250° C.; said amine being a mono- or polyamino aromatic, aliphatic, cycloaliphatic, or heterocyclic amine and where the mole ratio of said first reaction product to (C) is about 1:0.5 to about 1:3.2. A lubricating composition according to claim 1 wherein said oil-soluble, nitrogen-containing reaction product is present in an amount of about 0.05’% to about 10% by weight.3. A lubricating composition according to claim 1 where the oil-soluble, nitrogen-containing reaction product is prepared by first reacting (A) at least one acidic reactant selected from the class consisting of maleic acid, chloromaleic acid, alkylated maleic acid, itaconic acid, and the anhydrides and lower alkyl esters thereof with (B) at least one phosphosulfurized polyolefin wherein the polyolefin portion has a molecular weight of about 700 to about 5000 in an equivalent ratio of (A) to (B) of about 1:0.5 to about 1:3 at a temperature of about 100° C. to about 250° C. to form the first reaction product and subsequently reacting said first reaction product with (C) at least one alkylene poly amine having at least one primary or secondary amino group present therein at a temperature of about 50° C. to about 250° C.4. A lubricating composition according to claim 3 wherein said first reaction product is prepared by reacting (A) at least one acidic reactant selected from the group consisting of maleic acid and maleic anhydride with (B) phosphosulfurized polymer of 1-monoolefin.5. A lubricating composition according to claim 4 wherein the alkylene polyamine is ethylene polyamine.6. A lubricating composition according to claim 5 wherein said phosphosulfurized polymer of 1-monoolefin is phospho sulfurized polyisobutylene.7. A lubricating composition according to claim 6 wherein said oil-soluble, nitrogen-containing reaction product is present in an amount of about 0.1% to about 5 % by weight.
