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: Derivatized carbon monoxide (CO) copolymers (DCOC) are produced by reacting functionalized, linear, highly alternating copolymers of CO, hydroxy- or amino-functional 1-alkenes (A) and optionally 2-20C 1-alkenes (B) with electrophilic organic compounds (C) in an aprotic organic solvent. A process for the production of DCOC starting from functionalized, linear, highly alternating copolymers of CO with (A) 1-alkene(s) comprising (A1) aryl compounds substituted with terminal allyl or homoallyl unit(s) and hydroxyl or amino group(s) or (A2) alpha -unsaturated aliphatic alcohols, and optionally (B) 2-20C 1-alkene(s). The process comprises reacting these functional copolymers with (C) organic compounds containing electrophilic groups, in an aprotic organic solvent. Independent claims are also included for (a) derivatized CO copolymers (DCOC) obtained by this process; (b) a process for the production of graft copolymers by reacting DCOC with nucleophilic organic compounds in aprotic organic solvents; (c) graft copolymers obtained by this process; and (d) the use of functionalized, linear carbon monoxide copolymers as above for the production of DCOC.
