Method of polymerizing butadiene with the aid of a three component catalyst comprising a mixture of (1) a group ii or iii metal hydride orderivatives thereof,(2) an organonickel or cobalt compound and (3) a fluorine containing material
Abstract
Abstract A METHOD AND A CATALYST SYSTEM FOR THE SOLUTION POLYMERIZATION OF BUTADIENE OR BUTADIENE IN MIXTURE WITH OTHER DIOLEFINS TO FORM POLYMERS CONTAINING A HIGH CONTENT OF CIS-1,4 ADDITION IS DESCRIBED. THE SOLUTION POLYMERIZATION IS CARRIED OUT UNDER CONVENTIONAL POLYMERIZATION CONDITIONS. THE CATALYST EMPLOYED IS A MIXTURE OF (1) AT LEAST ONE COMPOUND SELECTED FROM THE GROUP CONSISTING OF HYDRIDES OF METALS OF GROUPS II AND III OF THE PERIODIC TABLE AND THEIR MONOMERIC OR POLYMERIC HALIDE DERIVATIVES, AMINE DERIVATIVES AND COMPLEXES OF THESE HYDRIDES WITH AMINES, ETHERS OR OTHER MOLECULES CAPABLE OF FORMING COMPLEX COMPOUNDS WITH THESE HYDRIDES, (2) AT LEAST ONE COMPOUND SELECTED FROM THE CLASS CONSISTING OF ORGANONICKEL AND ORGANOCOBALT COMPOUNDS AND (3) AT LEAST ONE FLUORINE CONTAINING COMPOUND SELECTED FROM THE GROUP CONSISTING OF BORON TRIFLUORIDE, BORON TRIFLUORIDE ADDITION COMPLEXES, METAL FLUORIDES, HYDROGENE FLUORIDE AND TRIALKYLTIN FLUORIDES.
