Process of producing cis-1,4 polybutadiene with a 3-component catalyst

Claim 1

A PROCESS FOR POLYMERIZING 1,3-BUTADIENE TO FORM A POLYBUTADIENE CONTAINING AT LEAST 85 PERCENT CIS 1,4-ADDITION WHICH COMPRISES CONTACTING 1,3-BUTADIENE UNDER POLYMERIZATION CONDITIONS WITH A CATALYST SELECTED FROM THE GROUP CONSISTING OF (1) A CATALYST WHICH FORMS ON MIXING (A) A COMPOUND HAVING THE FORMULA RNM, WHEREIN R IS A RADICAL SELECTED FROM THE GROUP CONSISTING OF ALKYL, CYCLOALKYL, ARYL, ARALKYL AND ALKARYL, M IS A METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM, GALLIUM, INDIUM AND THALLIUM, AND N IS AN INTEGER EQUAL TO THE VALENCE OF THE METAL M, (B) A TITANIUM HALIDE HAVING THE FORMULA TIX4, WHEREIN X IS A HALOGEN SELECTED FROM THE GROUP CONSISTING OF CHLORINE AND BROMINE, AND (C) AN INORGANIC IODIDE HAVING THE FORMULA M''IX, WHEREIN M'' IS A MEMBER SELECTED FROM THE GROUP CONSISTING OF ALUMINUM, AND ANTIMONY, AND X IS AN INTEGER EQUAL TO THE VALENCE OF M'' AND (2) A CATALYST WHICH FORMS ON MIXING (A'') A COMPOUND HAVING THE FORMULA RNM, WHEREIN R, M AND N ARE AS DEFINED ABOVE, (B'') TITANIUM TETRAIODIDE, AND (C'') AN INORGANIC HALIDE HAVING THE FORMULA M"XY, WHEREIN M" IS A MEMBER SELECTED FROM THE GROUP CONSISTING OF PHOSPHORUS, ANTIMONY, ARSENIC AND BISMUTH, X IS AS DEFINED ABOVE, AND Y IS AN INTEGER EQUAL TO THE VALENCE OF M", THE MOL RATIO OF SAID RNM COMPOUND TO SAID TITANIUM HALIDE AND SAID INORGANIC IODIDE BEING IN THE RANGE OF 1.25:1 TO 20:1, THE MOL RATIO OF SAID TITANIUM HALIDE TO SAID INORGANIC IODIDE BEING IN THE RANGE OF 0.05:1 TO 5:1, THE MOL RATIO OF SAID RNM COMPOUND TO SAID TITANIUM TETRAIODIDE AND SAID INORGANIC HALIDE BEING IN THE RANGE OF 1.25:1 TO 20:1 AND THE MOL RATIO OF SAID INORGANIC HALIDE TO SAID TITANIUM TETRAIODIDE BEING IN THE RANGE OF 0.5:1 TO 5:1.
