Abstract

An oil-soluble copolymer is prepared by copolymerizing (A) a vinyl ester or a hydrocarbyl substituted vinyl ester of a carboxylic acid and (B) a dialkyl ester of fumaric acid, maleic acid or itaconic acid and a monohydric alcohol or a mixture of monohydric alcohols in the presence of a minor proportion by weight, based on the total weight of (A) and (B), of an allyl compound of the formula CH2=CH.CH2OR where R is hydrogen, a hydrocarbyl group, a substituted hydrocarbyl group or -OCR1, where R1 is a hydrocarbyl group, or a substituted hydrocarbyl group, said hydrocarbyl groups being saturated aliphatic groups or aryl groups in which any substituent in any benzene ring is saturated. In the examples are used: vinyl acetate, allyl alcohol, mineral oil, a dialkyl fumarate prepared from hydrogenated fatty acid alcohol, a dialkyl fumarate prepared from mixed ceto-stearyl alcohol and azo-bis-isobutyronitrile. The coconut fatty acid alcohol and mixed ceto-stearyl alcohol comprise mixtures of C8, C10, C12, C14, C16 and C18 straight chain alcohols and C14, C16 and C18 straight chain alcohols respectively. The reaction is terminated by the addition of high sulphur mineral oil. Benzoyl peroxide is used in some examples. The copolymers may be used as lubricating oil additives.ALSO:A lubricating composition comprises a mineral lubricating oil and 0.01% to 10.0% by weight based on the oil of a copolymer prepared by copolymerizing (A) a vinyl ester or a hydrocarbyl substituted vinyl ester of a carboxylic acid, and (B) a dialkyl ester of fumaric acid, maleic acid or itaconic acid and a monohydric alcohol or a mixture of monohydric alcohols in the presence of a minor proportion by weight, based on the total weight of (A) and (B), of an allyl compound of the formula CH2=CHCH2OR where R is hydrogen, a hydrocarbyl group, a substituted hydrocarbyl group or -OCR1 where R1 is hydrocarbyl group or a substituted hydrocarbyl group, said hydrocarbyl groups being saturated aliphatic groups or aryl groups in which any substituent in any benzene ring is saturated. Fuel compositions comprising diesel fuel base stocks, domestic heating oils, or refined kerosene and the copolymers may also be prepared.
