<p>A process for preparing linear, alternating interpolymers of olefins and carbon monoxide (polyketones) comprises reacting carbon monoxide with one or more olefins in the presence of a catalyst prepared by reacting a source of palladium, with a bidentante amine, phosphine, arsine or stibine and a anion of a anion having the formula: <CHEM> wherein the R groups are independently selected from C1 to C6 alkylene groups, ortho-phenylene or biphenylene groups or groups having the formula: <CHEM> or substituted derivatives thereof. The process is characterised by being carried out in the presence of a quinone e.g. benzoquinone.</p> |
