Abstract: A process for preparing linear, alternating carbon monoxide copolymers, in which at least one olefinically unsaturated compound having from two to twenty carbon atoms (component K1) and carbon monoxide are copolymerized in the presence ofa) metal complexes,b) if desired, a protonic or Lewis acid, andc) if desired, a hydroxyl compound,comprises metering into the copolymerization, as it proceeds, at least one olefinically unsaturated compound having from two to twenty carbon atoms (component K2<>component K1) in the form of pulses, i.e. as a regular or irregular sequence of feed, for which the term pulse is used, and non-feed.Carbon monoxide copolymers obtainable from said process are used for producing fibers, films or moldings, and the fibers, films and moldings produced from these polymers are described.
