Polymerization of monoalkylethylenes

Claim 1

THE PROCESS FOR EFFECTING THE POLYMERIZATION OF MONOALKYLETHYLENES, WHICH COMPRISES SIMULTANEOUSLY PASSING A MONOALKYLETHYLENE, A SOLUTION OF ALUMINU, BROMIDE CATALYST IN A SOLVENT HAVING NO DELETERIOUS EFFECT ON THE POLYMERIZATION REACTION, AND A PROMOTOR FOR SAID ALUMINUM BROMIDE CATALYST INTO A POLYMERIZATION REACTION ZONE TO FORM A POLYMERIZATION REACTION MIXTURE AT RATES SUCH THAT, DURING THE COURSE OF THE POLYMERIZATION REACTION IN SAID POLYMERIZATION REACTION ZONE, THE MOL RATIO OF PROMOTER TO DISSOLVED ALUMINUM BROMIDE CATALYST WILL FALL WITHIN THE RANGE VARYING BETWEEN ABOUT 0.2 AND ABOUT 5. WHEN THE MONOALKYLETHYLENE IS PROPYLENE, AND BETWEEN ABOUT 0.05 AND ABOUT 1.6, WHEN THE MONOALKYLETHYLENE CONTAINS MORE THAN THREE CARBON ATOMS PER MOLECULE, AND THE RATE OF PASSAGE OF THE MONOALKYLETHYLENE INTO SAID POLYMERIZATION REACTION ZONE WILL BE NOT GREATER THAN ABOUT 2 MOLS PER MOL OF DISSOLVED ALUMINUM BRROMIDE CATALYST PER MINUTE, WHEN THE MONOAKLYLETHYLENE IS PROPYLENE AND NOT GREATER THAN ABOUT 4 MOLS PER MOL OF DISSOLVED ALUMINUM BROMIDE CATALYST PER MINUTE, WHEN THE MONOALKYLETHYLENE CONTAINS MORE THAN THREE CARBON ATOMS PER MOLECULE; MAINTAINING SAID POLYMERIZATION REACTION ZONE AT A TEMPERATURE FALLING WITHIN THE RANGE VARYING BETWEEN ABOUT -80* C. AND ABOUT 0* C., WHEN THE MONOALKYLETHYLENE IS PROPYLENE, AND BETWEEN ABOUT -45* C. AND ABOUT -100* C., WHEN THE MONOALKYLETHYLENE CONTAINS MORE THAN THREE CARBON ATOMS PER MOLECULE; DISCONTAINING THE PASSAGE OF SAID SOLUTION OF ALUMINUM BROMIDE CATALYST AND OF SAID PROMOTER INTO SAID POLYMERIZATION REACTION MIXTURE; PASSING ADDITIONAL AMOUNTS OF SAID MONOALKYLETHYLENE INTO SAID POLYMERIZATION REACTION MIXTURE ATT A RATE NOT GREATER THAN ABOUT 2 MOLS PER MINUTE PER MOL OF ALUMINUM BROMIDE CATALYST PRESENT IN SAID POLYMERIZATION REACTION MIXTURE, WHEN THE MONOALKYLETHYLENE IS PROPYLENE, AND NOT GREATER THAN ABOUTT 4 MOLS PER MINUTE PER MOL OF ALUMINUM BROMIDE CATALYST PRESENT IN SAID POLYMERIZATION REACTION MIXTURE, WHEN THE MONOALKYLETHYLENE CONTAINS MORE THAN THREE CARBON ATOMS PER MOLECULE; AND MAINTAINING SAID POLYMERIZATION REACTION MIXTURE AT A TEMPERATURE FALLING WITHIN THE RANGE VARYING BETWEEN ABOUT -80* C. AND ABOUT 0* C., WHEN THE MONOALKYLETHYLENE IS PROPYLENE, AND BETWEEN ABOUT -45* C. AND ABOUT -10* C., WHEN THE MONOAKLYLETHYLENE CONTAINS MORE THAN THREE CARBON ATOMS PER MOLECULE.
