The invention comprises an additive for lubricating oils (see Group III), said additive being a compound obtained by the sulphurization or sulphurization and phosphorization of the unsaponifiable matter extracted from saponified wool grease, or a metal salt of such a sulphurized and phosphorized compound. The unsaponifiable matter may be sulphurized by heating with sulphur and the reaction may be assisted by adding a small amount of sulphur monochloride or sulphur dichloride.

Alternatively, the unsaponifiable matter may be reacted with sulphur chlorides in oil or an inert solvent and the chlorine then replaced by sulphur, or phosphorus and sulphur, by reacting the product in a suitable solvent with sodium sulphide or polysulphide or the sodium salt of an organic dithiophosphoric acid. The sulphurization of the unsaponifiable material may be carried out in the presence of a vulcanization accelerator, e.g. mercaptobenzothiazole, benzothiazole disulphide, tetramethyl and tetraethyl thiuram disulphides or mixtures of these compounds with diphenyl guanidine.

Oil-soluble graft polymers derived from degraded ethylene-propylene interpolymers

1,244,435. Graft polymers. LUBRIZOL CORP. 29 April, 1969 [18 June, 1968], No. 21817/69. Heading C3G. [Also in Division C5] An oil-soluble polymer contains units derived from an oxygen-containing monomer grafted on to an oxidized, degraded interpolymer of ethylene and propylene, said oxidized, degraded interpolymer having a molecular weight of 1000 to 200,000 and being formed by contacting an ethylene-propylene interpolymer having a molecular weight of 50,000 to 800,000 with oxygen at a temperature of at least 100‹ C. for a period of time sufficient to effect a substantial reduction in the molecular weight of said interpolymer. The interpolymer, which is preferably derived from ethylene, propylene and a minor amount of a mono-olefin or polyene e.g. a non- conjugated diene, is oxidized and degraded by bubbling oxygen or air through a heated solution of the interpolymer, or by blowing air over the surface of the solution while the solution is subjected to shearing agitation. Alternatively, the degradation and grafting are effected simultaneously. Preferred graft monomers are vinyl esters of saturated carboxylic acids, N-vinyl lactams and N-oxohydrocarbon or sulphohydrocarbon acrylamides. In examples, (a) a degraded ethylene/propylene/1,4-hexadiene interpolymer is grafted with diethylaminoethyl methacrylate or decyl methacrylate; and (b) a degraded ethylene/propylene/dicyclopentadiene interpolymer is grafted with 2-hydroxyethyl methacrylate, vinyl acetate, N-vinylpyrrolidone, methacrylic acid, diethylaminoethyl methacrylate, an ester of methacrylic with an alcohol derived from a wax having a molecular weight of about 350, N - (1,1 - dimethyl - 3 - oxobutyl) acrylamide, a vinyl ester of a saturated carboxylic acid containing about 10 carbon atoms or 2 - acrylamido - 2 - methylpropane - 1 - sulphonic acid. The graft polymer obtained using methacrylic acid is reacted with N-(3-aminopropyl) morpholine. The graft polymers are incorporated in mineral oil lubricants.
