Friction or tractive drive containing ethers of adamantanes

Abstract

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): A. a tractant comprising a hydrocarbon dimer of an alkyladamantane and/or alkyladamantanol of the C.sub.12 -C.sub.19 range containing 1-3 alkyl groups of the C.sub.1 -C.sub.3 range, the dimer containing two adamantane nuclei which are linked to each other through an alkylene radical derived from and having the same number of carbon atoms as an alkyl group of the starting material; and B. an ether analogous to a hydrocarbon dimer from group (A) but in which there are two linkages between nuclei, one being an oxymethylene or oxyethylene radical, the other being a methylene or ethylene radical.
