    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.

    Abstract: The invention relates to catalyst systems for the copolymerisation of carbon monoxide and alpha -olefinically unsaturated compounds, containing as essential constituents a) a metal complex of the general formula (I), in which the rests R to R are linear or branched C2-C28 alkyl substituted by at least one polar functional group which is ionic or has a protonic action, on the basis of elements of groups IVA to VIA of the periodic table, C3-C14 cycloalkyl or alkyl aryl with between 1 and 28 C-atoms in the alkyl part and between 6 and 15 C-atoms in the aryl part; and b) possibly one or more Lewis or protonic acids or a mixture of Lewis and protonic acids.
