Abstract
For the preparation of interpolymers of ethylene with one or more polyene hydrocarbons, in which at least one unsaturation belongs to a polycyclic system, the reaction is carried out in the presence of a diluent and of a special catalytic system. The latter is prepared from 1 - one or more vanadium compounds of a valency greater than two, soluble in the reaction medium, 2 - one or more aluminium compounds of the general formula R2AlX in which R is an alkyl, cycloalkyl, alkylaryl or aryl radical having 1 to 12 carbon atoms and X is chlorine or bromine, and 3 - one or more of the following compounds: organic compounds containing the grouping -CCl3, hexachlorocyclopentadiene or thionyl chloride. The polymerisation yields relative to the vanadium compound are between 30,000 and more than 1,000,000 grams of copolymer per gram of vanadium, and the polymerisation product does not require a washing stage for removal of catalytic residues, but can be recovered from the reaction slurry by centrifuging or stripping. The unsaturated interpolymers thus obtained have a random distribution of the monomer units, a high mean molecular weight, a high crystallinity of the polyethylene type and a melting point above 120 DEG C.
