A method of separating a dicarbonyl treatment agent from a polymerization reaction medium in which it is present in chemical combination with metal catalyst residues, characterized by (a) intimately contacting said treatment agent with water at an elevated temperature in a reaction zone, (b) passing the reaction effluent containing said treatment agent to a separation zone in which said dicarbonyl treatment agent is separated from said effluent, and separating said treatment agent from the resulting upper stream. .
