Abstract

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: ##STR1## wherein the R groups are independently selected from C.sub.1 to C.sub.6 alkylene groups, ortho-phenylene or biphenylene groups or groups having the formula: ##STR2## or substituted derivatives thereof. The process is characterized by being carried out in the presence of a quinone e.g. benzoquinone.
