Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
125 words
A PROCESS FOR POLYMERIZING A NORMALLY GASEOUS OLEFIN WHICH COMPRISES CONTACTING SUCH AN OLEFIN UNDER POLYMERIZING CONDITIONS WITH A SUPPORTED NICKEL OXIDE CATALYST, SAID CATALYST HAVING BEEN MADE BY CONTACTING POROUS PARTICULATE SUPPORT WITH AN AQUEOUS SOLUTION OF A NICKEL COMPOUND READILY CONVERTIBLE TO THE OXIDE BY HEATING IN A NON-REDUCING AMBIENT SO AS TO ABSORB ON SAID SUPPORT BETWEEN 0.1 AND 10 WEIGHT PERCENT OF NICKEL IN THE FORM OF SAID COMPOUND, MAINTAINING SAID SOLUTION AT A TEMPERATURE IN THE RANGE OF 70*C. TO THE BOILING POINT THEREOF DURING THE CONTACTING STEP, DRYING THE RESULTING IMPREGNATED SUPPORT, THEREAFTER CONVERTING THE ADSORBED NICKEL COMPOUND TO THE OXIDE, AND THEREAFTER REPEATING, AT LEAST ONCE, THE CONTACTING, DRYING AND CONVERSION STEPS, SO AS TO FORM LIQUID POLYMER.
