Polymer slurry catalyst residue deactivation |
摘要 |
Catalyst residues of a transition metal compound and an organometalliccompound contained in a polymer slurry are deactivated by contact with anhydrous carbon dioxide. Preferably the contacting is carried out in a transfer line connecting the reaction zone with a zone of sufficiently lower pressure that flashing of diluent occurs in the transfer line to assure mixing of the carbon dioxide and the catalyst residues.
