    Abstract: A process for the production of linear, alternating carbon monoxide copolymers (I) comprises copolymerization of a 2-20C olefinically unsaturated compound (II) and carbon monoxide in the presence of a metal complex of formula whereby a further 2-20C olefinically unsaturated compound that is different to the first compound is added during the reaction in at least two separate doses. A process for the production of linear, alternating carbon monoxide copolymers (I) comprises copolymerization of a 2-20C olefinically unsaturated compound (II) and carbon monoxide in the presence of: (A) a metal complex of formula (1); (B) optionally a protonic or Lewis acid; and (C) optionally a hydroxy compound whereby a further 2-20C olefinically unsaturated compound (III) that is different to the compound (II) is added during the reaction in at least two separate doses. Independent claims are included for: (i) the resulting carbon monoxide copolymer (I); (ii) fiber , film or molded articles containing the copolymer (I). G = 5-7 membered carbocyclic ring, optionally containing heteroatoms; -(CRb2)r-, -(CRb2)s-Si(Ra)2-(CRb2)t, -A-O-B- or -A-Z(R )-B-; R = H, 1-28C alkyl, 3-14C cycloalkyl, 6-15C aryl or alkylaryl having 1-20C alkyl and 6-15C aryl, -N(Rb)2 or -S(Ra)3, optionally substituted; A, B = (CRb2)t-, -(CRb2)s-Si(Ra)2-(CRb2)t, -N(Rb)-, a r'-, S- or t- atom containing component of a ring system or together with Z forms a (r'+1)-, (s+1)- or (t+1)- atoms containing component of a heterocycle; Rn = 1-20C alkyl, 3-10C cycloalkyl, 6-15C aryl or alkylaryl having 1-10C alkyl and 6-15C aryl, optionally substituted; RbRa = H or Si(Ra)3; r = 1-4; r' = 1 or 2; s,t = 0-2; s+t = 1-3; Z = a Group 14 element; M = a Group 8-12 element; R -R = 1-28C alkyl, 3-14C cycloalkyl, 6-15C aryl or alkylaryl with 1-28C alkyl and 6-15C aryl, optionally substituted; L , L = neutral or charged ligand; X = mono- or multivalent anion; m, n, p = 0-3; p = m \* n

    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.
