Perhydrogenated dimers of styrene or a methylated styrene have very high coefficients of traction and are therefore useful as traction fluids. A preferred dimer is 1-cyclohexyl-1,3,3-trimethylhydrindane.

Traction fluids

A friction or tractive drive comprises at least two relatively rotatable members in torque transmitting relationship, the tractive surfaces of the members having disposed thereon a tractant selected from the following groups (A) or (B):

Friction or tractive drive containing ethers of adamantanes

4,9-Cis-1-cyclohexyl-1,3,3-trimethylhydrindane is a new compound and is a fluid with improved tractive properties.

4,9-Cis-1-cyclohexyl-1,3,3-trimethylhydrindane

A composition useful as a base stock for a lubricant in a traction drive transmission has a kinematic viscosity at 210.degree.F in the range of 1.5-200.0 cs. and contains A. from 1-25 parts by weight of a hydrogenated polymer of C.sub.3 -C.sub.8 aliphatic monoolefin, said polymer having an average molecular weight in the range of 180-2000, and B. one part by weight of at least one member selected from
