Abstract

- 1 3 0 - PROCESS FOR PRODUCING POLYBUTADIENE RUBBER AND RUBBER COMPOSITION ABSTRACT APROCESS FORPRODUCING A VINYL-CIS-POLYBUTADIENE RUBBER, 5 INCLUDING MIXING (A) VINYL-CIS-POLYBUTADIENE OBTAINED BY (1) A STEP OF ADDING A CIS-1,4-POLYMERIZATION CATALYST OBTAINABLE FROM AN ORGANOALUMINUM COMPOUND AND A SOLUBLE COBALT COMPOUND TO A MIXTURE CONTAINING 1, 3-BUTADIENE AND A HYDROCARBON-BASED ORGANIC SOLVENT AS THE MAJOR COMPONENTS AND HAVING AN ADJUSTED 10 WATER CONTENT, THEREBY SUBJECTING THE 1,3-BUTADIENE TO CIS-1,4-POLYMERIZATION AND SUBSEQUENTLY, (2) A STEP OF MAKING A CATALYST OBTAINABLE FROM A SOLUBLE COBALT COMPOUND, AN ORGANOALUMINUM COMPOUND REPRESENTED BY THE GENERAL FORMULA, ALR3 (WHEREIN R REPRESENTS AN ALKYL GROUP HAVING FROM I TO 6 15 CARBON ATOMS, A PHENYL GROUP, OR A CYCLOALKYL GROUP) , AND CARBON DISULFIDE PRESENT IN THE RESULTING POLYMERIZATION REACTION MIXTURE, THEREBY SUBJECTING THE 1,3-BUTADIENE TO 1,2-POLYMERIZATION; AND (B) CIS-POLYBUTADIENE OBTAINED BY A STEP OF ADDING THE FOREGOING CIS-1,4-POLYMERIZATION CATALYST, 20 THEREBY SUBJECTING THE 1,3-BUTADIENE TO CIS-1,4-POLYMER- IZATION AND A RUBBER COMPOSITION CONTAINING THE RESULTING RUBBER.
