| 摘要 |
The present invention relates to a production method for aliphatic polyketone wherein the ethylene and carbon monoxide monomers are polymerized by perfectly alternating copolymerization under high pressure in water using a palladium-diphosphine catalyst, and which comprises the steps of preparing the catalyst mixture (11), preparing the solvent (111), purging the solvent with gas (112), adding palladium salt into the solvent (113), adding a phosphorous or nitrogen based bidentate ligand (114), stirring the mixture (115), adding acid anion (116), continuing to stir (117), adding catalyst mixture into the reactor containing water (12), purging the reactor with gas (13), adjusting the reaction temperature (14), adding the ethylene-carbon monoxide gas mixture (15), carrying out polymerization (16), filtering the obtained polymer (17), washing the polymer (18), drying the polymer (19). |
