Diolefin polymerization catalysts using a metalliferous component, a catalyst regulator and aix

Claim 1

A PROCESS FOR PRODUCING A SUBSTANTIALLY ALL 1,4 ADDIION POLYBUTADIENE PRODUCT COMPRISING POLYMERIZING MONOMERIC 1,3-BUTADIENE IN A SUBSTANTIALLY DRY, INERT ATMOSPHERE, AT A TEMPERATURE BELOW ABOUT 100*C. AND IN THE PRESENCE OF A REACTION SOLUBILIZING INERT HYDROCARBON POLYMERIZATION MEDIUM WITH A CATALYST COMPOSITION COMPRISED OF AN ALUMINUM TRIHALIDE; A METALIFEROUS COMPONENT SELECTED FROM THE GROUP CONSISTING OF METALS AND COMPOUNDS OF MEALS OF BERYLLIUM, MAGNESIUM, COBALT, NICKEL, TITANIUM, VANADIUM, CHROMIUM, MANGANESE, IRON, PLATINUM AND PALLADIUM; AN ALKALI METAL HALIDE; AND A THIOPHENE CATALYST REGUALATOR COMPONENT SELECTED FROM THE GROUP CONSISTING OF THIPHENE AND ALIPHATIC HYDROCARBON SUBSTITUTED THIOPHENE, THE COMPONENTS OF SAID CATALYST BEING PRESENT IN A RATIO SUCH THAT, ON A MOLAR BASIS, THE ALUMINUM TRIHALIDE CONSTITUTES AT LEAST ABOUT TWICE THE AMOUNT OF THE METALLIFEROUS COMPONENET, AT LEAST ABOUT TWICE THE AMOUNT OF THE ALKALI METAL HALIDE COMPONENT, BUT NO MORE THAN ABOUT TWICE THE AMOUNT OF THIOPHENE CATALYST REGULATOR COMPONENT EMPLOYED, AND AT LEAST ABOUT ONE MOLE OF ALUMINUM TRIHALIDE IS PRESENT FOR EVERY 300 MOLES OF SAID BUTADIENE.
