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.
