Claim 1
Independent Claim
115 words
IN THE POLYMERIZATION OF ALIPHATIC A-MONOOLEFINIC HYDROCARBON MATERIAL CONTAINING 2-10 CARBON ATOMS TO FORM SOLID POLYMER, THE IMPROVEMENT WHICH COMPRISES EFFECTING THE POLYMERIZATION IN THE PRESENCE OF A CATALYST MIXTURE COMPRISING (1) A METAL FROM THE GROUP CONSISTING OF ALUMINUM, ZINC AND MAGNESIUM, (2) A COMPOUND OF THE FORMULA M(R)4 WHEREIN M IS FROM THE GROUP CONSISTING OF LEAD, TIN AND SILICON AND R IS AN ALKYL GROUP OF 1-12 CARBON ATOMS, AND (3) A TITANIUM TETRAHALIDE, THE MOLAR RATIO OF SAID COMPOUND M(R)4 TO SAID METAL BEING IN THE RANGE OF FROM 1:4 TO 4:1, THE MOLAR RATIO OF SAID TITANIUM TETRAHALIDE TO EACH OF THE OTHER CATALYST COMPONENTS BEING FROM 1:4 TO 2:1.
