Abstract

Lubricating and fuel oil compositions comprise a mineral oil and an oil-soluble copolymer derived from 1 to 10 parts (by weight) of maleic anhydride, 10 to 30 parts of an ester of a vinyl alcohol and a C2-12 monocarboxylic acid, and 50 to 90 parts by weight of an ester of fumaric or maleic acid and a C8-18 alcohol. The C8-18 alcohol is preferably a natural alcohol, e.g. palm kernel alcohol or lauryl alcohol. The compositions may be oil concentrates of the polymers, which when present as about 5 per cent wt. of the final oil impart good pour point, viscosity index and detergency characteristics to the oil. Optional additives mentioned are oil-soluble sulphonates, metal salts of alkyl phenol sulphides and E.P., anti-wear and anti-oxidant additives. Examples comprise a mineral oil having viscosities of 180 cs./100 DEG F. and 12 cs./210 DEG F. (V.I. = 104) and copolymers prepared from the following ingredients at 60 DEG C. under reflux for 24 hours using 2 per cent benzoyl peroxide as catalyst: (i) 75 parts (weight) lauryl fumarate, 19 parts vinyl acetate, 4 parts maleic anhydride, and 2 parts lauryl alcohol; and (ii) 79, 16, 3 and 2 parts respectively of the same monomers. The Provisional Specification refers to the similar use of copolymers of maleic anhydride with one or more copolymerizable organic compounds. Examples of such compounds are vinyl esters of C3-20 acids e.g. of tiglic, acrylic, methacrylic, oleic or lauric acids; unsaturated hydrocarbons e.g. simple C3-10 mono olefines, polymerized olefines e.g. ethylene or alkylated styrene, and diolefines e.g. isoprene, ethers and acrylonitrile. The use of the copolymers in animal or vegetable oils or synthetic lubricating oils such as complex esters and diesters is also mentioned.ALSO:Lubricating and fuel oil compositions comprise a mineral oil and an oil-soluble copolymer derived from 1 to 10 parts (by weight) of maleic anhydride; 10 to 30 parts of an ester of a vinyl alcohol and a C2-12 monocarboxylic acid; and 50 to 90 parts by weight of an ester of fumaric or maleic acid and a C8-18 alcohol.
