Abstract: Homopolymers of monoolefins, diolefins, acrylates, methacrylates, vinyl esters, vinyl ethers, or esters of a -, b -unsaturated dicarboxylic acids, copolymers of olefins with other olefins, diolefins, styrene, or unsaturated esters, copolymers of unsaturated esters, copolymers of vinyl esters and unsaturated esters, and terpolymers of vinyl acetate, octyl fumarate and maleic anhydride may all be reacted with iodine (solid, dissolved, or vapour) at 20 DEG to 200 DEG  F. for 0.1 to 100 hours, to produce additives containing from 0.5% to 90% of iodine which may be added to the lubricating oils. Preferred polymers are polybutene, phosphosulphurized polybutene, and ethoxylated hydrolysed phosphosulphurized polybutene.ALSO:A composition for use as a lubricant comprises a major proportion of a carrier medium and 0.009 to 0.09% by weight of iodine.  The carrier may be a paraffinic, naphthenic, asphaltic, mixed-base or blended mineral oil, (including lubricating oil, fuel oil, gas oil, kerosene, jet fuel or gasoline) paraffin wax, petrolatum or grease, or synthetic oil made from esters, polysiloxanes, carbonates, formals, or polyglycols or mixtures of such mineral and synthetic oils, it may comprise a lubricating oil, cutting oil, metal working oil, hydraulic fluid, pneumatic equipment oil, spindle oil, or gear oil; it may also be water or an aqueous solution of an iodide or polyhydroxy compound (e.g. starch, amylose, amylopectin, sorbitol or polyethylene glycol), which may also contain nitrites, chromates, phosphates, imidazolines, sulphonates, or amines as corrosion inhibitors, wetting agents, or mutual solvents such as alcohols or ethers. The iodine may be added by dissolving solid iodine, adding a solution of iodine, bubbling iodine vapour through the carrier, or adding a complex of iodine with a heterocyclic nitrogen compound, an ether (including cyclic ethers), an alcohol, a ketone, an acid, an ester (including silicates and carbonates), an aldehyde or a polymer containing any of these functional groups. (Many specific examples are given). Sulphonic acids and salts may also be used.  Polymeric additives.-Homopolymers of mono-olefins, diolefins, acrylates, methacrylates, vinyl esters, vinyl ethers, or estersof a -, b -unsaturated dicarboxylic acids, copolymers of olefins with other olefins, diolefins, styrene, or unsaturated esters, copolymers of unsaturated esters, copolymers of vinyl esters and unsaturated esters, and terpolymers of vinyl acetate, octyl fumarate and maleic anhydride may all be reacted with iodine (solid, dissolved, or vapour) at 20 DEG  to 200 DEG  F. for 0.1 to 100 hours to produce additives containing from 0.5% to 90% of iodine which may be added to the oils.  Preferred polymers are polybutene, phosphosulphurized polybutene, and ethoxylated hydrolysed phosphosulphurized polybutene.  Optional additives include phenothiazine, phenylalphanaphthylamine, the barium salt of isononyl pheno sulphide, copolymers of vinyl acetate with fumaric acid esters of coconut oil alcohols, polymethacrylates, barium petroleum sulphonate, alkyl aryl sulphonates, alkyl phenates, alkyl phenol sulphides, phosphosulphurized polyolefins, cadmium naphthenate, oleic acid, heat thickened fatty oils, sulphurized fatty oils organometallic compounds, resins, rubber, other polymers, colloids, dyes and soaps.
