    Abstract: A method is described whereby olefin terpolymers, consisting of ethylene, an alpha olefin and a polyene having in the molecule, in addition to the double bond participating in the formation of the macromolecule, at least one conjugated double bond system, are stabilied against oxidative aging without destroying their characteristic high vulcanization rate by reacting them with a dienophilic agent represented by one of the following formulae:

    WHEREIN R and R6 may be an alkyl, alkenyl, cycloalkyl, aryl or aralkyl radical having up to 8 carbon atoms, R1, R2, R3, R4 and R5 may be hydrogen or alkyl, aryl, cycloalkyl or aralkyl radicals having up to 8 carbon atoms, the R1-R2 and R-R pairs may be divalent radicals forming condensed rings.

    Abstract: Synthetic, high quality lubricating oils are produced through the polymerization of a single alpha-olefin or a mixture of alpha-olefins from ''''wax-cracking'''' having the formula R - CH CH2 wherein R is an alkyl radical containing from 2 to 16 C atoms, by the use, in a dry nitrogen atmosphere, of a catalyst system constituted by a compound of a transition metal selected from groups IV to VIII of the periodic system (e.g., TiCl4) and by two coordinate anionic cocatalysts, one of which is an aluminum compound of inorganic nature devoid of any metal-carbon bond and consisting of a polyiminic linear polymer (e.g., a polyimine alane represented by the formula:

    WHEREIN R is alkyl, aryl or cycloalkyl and n is a whole number from 4 to 25) and the other of which is an aluminum compound of the conventional Ziegler type with a metal-carbon link (e.g., an aluminum alkyl sesquichloride or an aluminum dialkyl monochloride.
