Claim 1
Independent Claim
147 words
METHOD FOR THE POLYMERIZATION OF ETHYLENICALLY UNSATURATED HYDROCARBONS WHICH COMPRISES CONTACTING AT LEAST ONE ETHYLENICALLY UNSATURATED HYDROCARBON WITH A CATALYST COMPOSED OF A MIXTURE OF A FIRST AND SECOND COMPONENT, SAID FIRST COMPONENT BEING SUBSTANTIALLY COMPOSED OF A MEMBER OF THE GROUP CONSISTING OF ALKALI METAL ALKYLS AND, -ARALKYLS, COMPLEXES OF ALKALI METAL ALKYLS WITH A METAL ORGANO COMPOUND OF THE GROUP OF METALS CONSISTING OF MAGNESIUM AND ZINC, AND COMPLEXES OF ALKALI METAL HYDRIDES WITH A METAL ORGANO COMPOUND OF SAID GROUP OF METALS AND COMPLEXES CONSTITUTED OF TWO METAL ORGANO COMPOUNDS OF SAID GROUP OF METALS AND OF ALUMINUM, SAID SECOND COMPONENT BEING A HEAVY METAL COMPOUND SELECTED FROM THE GROUP CONSISTING OF THE SALTS AND THE FRESHLY PRECIPITATED OXIDES AND HYDROXIDES OF METALS OF GROUPS IV-B, V-B AND VI-B OF THE PERIODIC SYSTEM, INCLUDING THORIUM AND URANIUM, AND RECOVERING THE HIGH MOLECULAR POLYMER FORMED.
