Abstract: THERE ARE DISCLOSED HIGH-MOLECULAR WEIGHT COPOLYMERS OF AT LEAST ONE POLYCYCLIC POLYENE HAVING CONDENSED NUCLEI AND IN WHICH EACH PAIR OF CONDENSED NUCLEI HAS TWO CARBON ATOMS IN COMMON, AND AT LEAST ONE MONOMER SELECTED FROM THE GROUP CONSISTING OF ETHYLENE AND HIGHER ALPHA-OLEFINS OF THE GENERAL FORMULA R-CH2=CH2, WHEREIN R IS AN ALKYL GROUP CONTAINING 1 TO 6 CARBON ATOMS, AND MORE PARTICULARLY SUCH SUBSTANTIALLY LINEARAMORPHOUS COPOLYMERS WHICH ARE CAPABLE OF BEING VULCANIZED. ALSO DISCLOSED IS A PROCESS FOR PREPARING THE LINEAR AMORPHOUS HIGH-MOLECULAR WEIGHT COPOLYMERS CAPABLE OF BEING VULCANIZED. THE PROCESS COMPRISES THE USE OF CATALYSTS ACTING WITH A COORDINATE ANIONIC MECHANISM.

Abstract: New and novel copolymerizates of ethylene and/or aliphatic alpha-olefins containing three to eight carbon atoms with nonconjugated diolefins containing at least one terminal unsaturation of vinyl type are disclosed. The copolymerizates are obtained by copolymerizing nonconjugated aliphatic diolefins containing at least one vinyl unsaturation and from five to 15 carbon atoms with ethylene or with ethylene and aliphatic alpha-olefins containing three to eight carbon atoms in the liquid phase but in the absence of halogenated aliphatic hydrocarbons, with a catalyst prepared from particular vanadium compounds and alkyl aluminum halides, both the preparation of the catalyst and the copolymerization being carried out a temperature between -80*C and +10*C.

Abstract: THERE IS DISCLOSED A PROCESS FOR POLYMERIZING UNSATURATED HYDROCARBONS OF THE FORMULA

CH2=CHR

IN WHICH R IS A SATURATED ALIPHATIC, AN ALICYCLIC OR AN AROMATIC RADICAL, ALONE, IN MIXTURES WITH ONE ANOTHER, OR IN MIXTURES WITH SMALL AMOUNTS OF ANOTHER MONOMER COPOLYMERIZABLE THEREWITH. IN THE FORMULA GIVEN R MAY BE, IN SPECIFIC MODIFICATIONS, AN ALKYL, CYCLOALKYL OR ARYL RADICAL. THE PROCESS INVOLVES POLYMERIZING THE UNSATURATED HYDROCARBONS, ALONE OR IN THE MIXTURES, IN CONTACT WITH A CATALYST PREPARED FROM A HALIDE OF A TRANSITION METAL BELONGING TO GROUPS IV TO VI INCLUSIVE OF THE MENDELEEFF PERIODIC TABLE AND AN ALKYL COMPOUND OF A METAL BELONGING TO GROUPS II AND III OF SAID TABLE, IN THE PRESENCE OF THE MONOMER.
