Abstract
PURPOSE: To prepare colorless liquid polybutadiene by treating a polymerization reaction mixture containing liquid polybutadiene successively with NaOH, a hypochlorite, and methanol.
CONSTITUTION: A polymerization reaction mixture containing a liquid polybutadiene having a viscosity of 100W10,000 cp (at 30°C) obtained by the polymerization of 1,3-butadiene in a thdrocarbon solvent in the presence of a catalyst prepared from a halogen-containing organic aluminum compound, a soluble Co compound, and an organo-phosphorus compound, is mixed with an aqueous solution of sodium hydroxide or potassium hydroxide, and the water layer is separated and removed. The oil layer containing the polymer is made to contact with an aqueous solution of a hypochlorite or hydrogen peroxide, and the water layer is removed. The oil layer containing the polymer is distilled to remove the dydrocarbon solvent, and the remaining liquid polybutadiene is washed with methanol to obtain purified polybutadiene
