Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
83 words
A PROCESS FOR POLYMERIZING AN ALPHA OLEFIN HAVING FROM 2 TO 20 CARBON ATOMS WHICH COMPRISES THE STEPS OF CONTACTING SAID ALPHA OLEFIN IN A HYDROCARBON DILUENT OF CONTACTING SAID ALPHA OLEFIN IN A HYDROCARBON DILUENT AT A TEMPERATURE OF FROM 0 TO 150*C. WITH A POLYMERIZATION CATALYST COMPRISING A TRANSITION METAL COMPOUND SELECTED FROM THE GROUP CONSISTING OF TITANIUM AND VANADIUM HALIDES AND OXYHALIDES COCRYSTALLIZED WITH THE CORRESPONDING CUPROUS HALIDE, AND ACTIVATED WITH AN ORGANO METALLIC COMPOUND TO POLYMERIZE SAID ALPHA OLEFIN.
Claim 2
Dependent Claim
83 words

Claim 3
Dependent Claim
85 words
THE PROCESS FOR POLYMERIZING AT LEAST ONE ALPHA OLEFIN HAVING FROM 2 TO 20 CARBON ATOMS WITH A C6 TO C15 NON-CONJUGATED DIOLEFIN WHICH COMPRISES CONTACTING SAID ALPHA OLEFIN AND DIOLEFIN IN A HYDROCARBON DILUENT AT A TEMPERATURE OF FROM ABOUT -40 TO 150*C. WITH A POLYMERIZATION CATALYST COMPRISING A TRANSITION METAL COMPOUND SELECTED FROM THE GROUP CONSISTING OF TITANIUM AND VANADIUM HALIDES AND OXYHALIDES COCRYSTALLIZED WITH THE CORRESPONDING CUPROUS HALIDE, AND ACTIVATED WITH AN ORGANO METALLIC COMPOUND TO POLYMERIZE SAID ALPHA OLEFIN AND DIOLEFIN.
