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

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

Blended traction fluid containing hydrogenated polyolefin and an

A method is disclosed for preparing a porous structure of ultra high molecular weight polyethylene. A heterogeneous composite of the polyethylene and a particular hydrocarbon is heated to a temperature above the melting point of the hydrocarbon but below the melting point of the polyethylene. The composite is then shaped. After such shaping the temperature is then raised to a temperature above the melting point of the polyethylene and maintained until complete fusion of the polyethylene particles occurs. Thereafter the hydrocarbon is extracted from the cooled shaped structure.
