Abstract
PURPOSE: To effectively prevent scale from depositing on polymerizer walls, by carrying out the polymerization by adding a specified compound in the polymerization of 1,3-butadiene using a catalyst comprising an organoaluminum compound-cobalt compound-water system.
CONSTITUTION: In the production of cis-1,4-polybutadiene by polymerizing 1,3- butadiene with the aid of a catalyst system comprising an organoaluminum compound, e.g., diethylaluminum chloride, a cobalt compound, e.g., cobalt chloride, and water, the polymerization is carried out by adding, to the reaction system, about 0.001W2mol times the organoaluminum compound contained in the catalyst components, of an alcohol or a ketone, e.g., methanol or acetone, as a scale deposition- preventing agent.
