Process for the removal of catalyst remnants from copolymers of carbon monoxide with one or more olefinically unsaturated compounds, which copolymers have been prepared by using a palladium- or nickel-containing catalyst composition, characterized in that the copolymers are treated with a complexing agent for palladium or nickel at a temperature of at least (T + 10)°C, in which T is the temperature, in °C, at which the copolymerization to produce the copolymers, has been carried out. |
