    摘要： Oil soluble viscosity index improving ethylene copolymers, such as copolymers of ethylene and propylene; and ethylene, propylene and diolefin; etc., are reacted or grafted with ethylenically unsaturated carboxylic acid moieties, preferably maleic anhydride moieties, and reacted with polyamines having two or more primary amine groups and a branched carboxylic acid component, preferably alkylene polyamine and branched monocarboxylic acid having 2 to 6 aliphatic hydrocarbon branches of 8 to 24 carbons each. Or the grafted ethylene copolymer can be reacted with already formed salts, and amides, etc. of said polyamine and branched acid component. These reactions can permit the incorporation of varnish inhibition and dispersancy into the ethylene copolymer while inhibiting cross-linking with resulting viscosity increase, haze or gelling. The aforesaid grafting reaction may be carried out thermally, or more preferably with a free radical initiator such as a peroxide in a mineral lubricating oil, in which case the branched acid component, preferably also acts to solubilize insoluble compounds formed by side reactions, such as maleic anhydride grafted oil molecules reacted with amine, to thereby inhibit haze formation, particularly when preparing oil concentrates of the V.I.-dispersant additive for later addition to lubricating oils.

    摘要： Oil-soluble copolymers with interlinked chains may be prepared by reacting (A) an ester of a monohydric alcohol containing 4 to 30 carbon atoms and an unsaturated carboxylic acid; (B) a monoester of a polyhydric alcohol and an unsaturated carboxylic acid and (C) a compound containing two olefinic double bonds, the ratio of the number of units C to the total number of units A and B being at least 1 to 2,000. Alternatively the copolymers may be obtained by copolymerizing monomer A or monomers A and B with an unsaturated carboxylic acid and esterifying the product with a polyhydric alcohol or alkylene oxide or by reacting a copolymer of monomer A and B with a carboxyl containing polymer. Monomer A may be an ester of acrylic, methacrylic, crotonic, tiglic, angelic, maleic, fumaric, mesaconic, citraconic or itaconic acid; and monomer an ester of such acids with ethylene glycol, propylene glycol, glycerine, erythritol, pentaerythritol or mannitol. Monomer C may be an ester of a dicarboxylic acid and an unsaturated alcohol, an ester of a polyhydric alcohol and an unsaturated carboxylic acid, a dialkenyl ether or a hydrocarbon, e.g. esters of ethylene glycol, propylene glycol, erythritol, pentaerythritol or mannitol with acrylic, methacrylic, crotonic, tiglic or angelic acids; divinyl, diallyl and dipropenyl esters and ethers; conjugated diolefins and divinyl and diallyl benzenes. Copolymerization may be effected in solution, e.g. in benzene or mixtures of benzene and isopropanol, in the presence of catalysts, e.g. benzoyl peroxide; the monomers being added incrementally. In examples (I) stearyl methacrylate, lauryl methacrylate, 2-hydroxyethyl methacrylate and ethylene glycol dimethacrylate are copolymerized; (II) stearyl methacrylate, lauryl methacrylate, ethylene glycol dimethacrylate and methacrylic acid are copolymerized and the copolymer reacted with ethylene oxide; (III) a copolymer of stearyl methacrylate, lauryl methacrylate and methacrylic acid is reacted with ethylene oxide; (IV) a copolymer of stearyl methacrylate, lauryl methacrylate and 2-hydroxyethyl methacrylate is reacted with a copolymer of stearyl methacrylate and methacrylic acid; and stearyl methacrylate, lauryl methacrylate and 2-hydroxyethyl methacrylate are copolymerized with (V) divinyl adipate and (VI) divinyl benzene. The products may be added to mineral and synthetic lubricating oils and greases, fatty oils and liquid fuels.ALSO:Fuel and lubricating oil compositions comprise oil-soluble copolymers with interlinked chains derived from monomeric components (A) an ester of a monohydric alcohol containing 4 to 30 carbon atoms and an unsaturated carboxylic acid, (B) a monoester of a polyhydric alcohol and an unsaturated carboxylic acid, and (C) a compound containing two olefinic double bonds, the ratio of the number of units C to the total number of units A and B being at least 1 to 2000.
