Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
109 words
THE METHOD OF POLYMERIZING TO A SOLID POLYMER AN ALPHA OLEFIN HAVING NO LESS THAN 2 CARBON ATOMS AND NO MORE THAN 8 CARBON ATOMS PER MOLECULE TO A SOLID POLYMER PRODUCT THAT COMPRISES REACTING SAID OLEFIN IN AN INAERT SOLVENT CONTAINING A CATALYST COMPRISING THE PREFORMED ALUMINUM HALIDE-METAL REACTION PRODUCT OBTAINING BY REACTING UNDER INERT CONDITIONS AND AT A TEMPERATURE IN THE RANGE OF FROM ROOM TEMPERATURE TO ABOUT 400*C. A MIXTURE CONSISTING ESSENTIALLY OF AN ALUMINUM HALIDE AND A METAL SELECTED FROM THE GROUP CONSISTING OF COBALT AND NICKEL, SAID MIXTURE CONTAINING 0.01-100 PARTS BY WEIGHT OF SAID ALUMINUM HALIDE PER PART BY WEIGHT OF SAID METAL.
