Abstract: POLAR COMPOUNDS CONTAINING A GEM-STRUCTURED HYDROCARBON "BACKBONE" ARE USEFUL AS TRACTION FLUIDS OR AS COMPONENTS OF TRACTION FLUIDS. FOR EXAMPLE, COMPOSITIONS, USEFUL AS ADDITIVES TO LUBRICANTS (E.G., COMPONENTS OF TRACTION FLUIDS), ARE PRODUCED BY OZONOLYSIS OF POLYOLEFINS, PARTICULARLY OF POLYISOBUTYLENE OLIGIMERS CONTAINING AT LEAST ONE PAIR OF MAXIMALLY CROWDED GEMINAL METHYL GROUPS. FOR EXAMPLE, OZONOLYSIS OF THE NOVEL POLYISOBUTYLENES CAN PRODUCE OXYGENATED DERIVATIVES (KETONES, ESTERS, ACIDS, ALDEHYDES, ALCOHOHOLS, ETC.) WHICH ARE USEFUL AS COMPONENTS OF TRACTION FLUIDS. ONE SUCH ALCOHOL IS 1,1,3,3,5,5,7,7,-OCTAMETHYL-1-OCTANOL. OTHER COMPOUNDS ARE 4,4,6,6,8,8-HEXAMETHYL - 2 - NONANONE AND 2,2,6,6,8,8-HEXAMETHYL-4-NONANONE. BLENDS OF THE KETONES OR OF MIXTURES OF THE ACIDS AND KETONES WITH A BASE OIL (E.G., PARAFFINIC LUBE, NAPHTHENIC LUBE, A HYDROGENATED NAPHTHENIC OR PARAFFINIC LUBE, POLYOLEFINS OR HYDROGENATED POLYOLEFINS) ARE ESPECIALLY USEFUL AS TRACTION FLUIDS OR AS A LUBRICANT FOR A FRICTION DRIVE OR A LIMITED SLIP DIFFERENTIAL.
