Process for preparing polyketones

A process for preparing polyketones by polymerising a mixture of carbon monoxide and one or more olefins in the presence of a group VIII metal catalyst which is prepared by reacting together: (a) a source of a group VIII metal, and (b) an amine, phosphine, arsine or stibine, characterised in that th...

Zusammenfassung:	A process for preparing polyketones by polymerising a mixture of carbon monoxide and one or more olefins in the presence of a group VIII metal catalyst which is prepared by reacting together: (a) a source of a group VIII metal, and (b) an amine, phosphine, arsine or stibine, characterised in that the polymerisation is carried out in the presence of a hydrocarbyl aluminoxane is disclosed. The group VIII metal is preferably palladium. The aluminoxane can be of the formula [(R R Al)2O]n'' or [R AlO]n''+2, where n'' is 2-40 and R , R and R are independently a C1-C20 hydrocarbyl group.
