Abstract: A traction fluid having a lubricant basestock comprising a selected mineral oil composition containing a saturate fraction having a significant portion made up of multiring components of at least three rings and an aromatic fraction which comprises at least 15% by weight of said composition and contains at least 40% by volume of multiring components.

Abstract: A fluid for traction drive is described, containing a liquid material as a base stock wherein the liquid material is prepared by bringing naphthalene or tetralin into contact with a Friedel-Crafts catalyst and then hydrogenating the resulting compounds. This traction drive fluid exhibits a superior traction coefficient from low temperature to elevated temperature and further has a low viscosity. Thus the fluid contributes to the production of small-sized drive mechanisms and can be widely used in various machines.

Abstract: Elastomeric polymers are rendered more tractable, thereby decreasing the amount of vehicle or heat required for vehicle- or melt-deposition, while resulting in very little or no loss of strength of the polymer, by the use of at least one compound comprising at least three hydrocarbon rings including at least one aromatic ring and, in most embodiments, at least one saturated ring free to rotate independently of at least one aromatic ring in the molecule of that compound. Compositions comprising an elastomeric polymer and at least one such compound are especially attractive for use in solvent, latex and/or hot melt adhesive compositions.

Abstract: New organo-lithium initiators, their synthesis, and their use. The initiators have the formula: ##STR1## in which R" is either a hydrogen atom or a methyl radical; either n is 1, in which case R' = H and m and p are integers, the sum of which is between 0 and 10 inclusive, or n is 2, R' then being an alkyl radical of 2 to 8 carbon atoms and m =p =0; and R is an alkyl radical of 1 to 4 carbon atoms.The initiators are prepared by reacting compounds of the formula: ##STR2## with an alkyl-lithium RLi in a non-polar solvent in the absence of any polar solvent or complexing agent.The initiators are used to prepare polydienes of high stereoregularity by reacting with a diene, and the polydiene is used to prepare a three-block or star copolymer by reacting with an anionically polymerizable monomer.
