POLYMERIZATION OF CO/OLEFIN WITH INCREASED CATALYST COMPOSITION CONCENTRATION DURING POLYMERIZATION START UP

Polyketone polymers are prepared in a continuous process by polymerising carbon monoxide and one or more olefinically unsaturated compounds, which are fed to the reactor at steady state flow rates. The start-up is performed by feeding the catalyst at a lower flow rate and/or feeding the diluent at a...

More Information
Summary:Polyketone polymers are prepared in a continuous process by polymerising carbon monoxide and one or more olefinically unsaturated compounds, which are fed to the reactor at steady state flow rates. The start-up is performed by feeding the catalyst at a lower flow rate and/or feeding the diluent at a higher flow rate. This results in a product of higher bulk density.
