    Abstract: The invention relates to a method for carrying out the transition metal-catalyzed production of polymers having a syndiotactic or predominantly syndiotactic structure from vinyl aromatic monomers. The invention also relates to a method for producing block copolymers from vinyl aromatic monomers and from olefinically unsaturated polar monomers. According to the invention, transition metal compounds of general formula (I) are used in which the substituents and indices have the following meanings: M represents scandium, yttrium, lanthanum or a lanthanoid metal; R''' represents pi -C3 to C20 alkyl; L represents a low-molecular, Lewis-basic organic compound, whereby n1 and n2 = 0 or n1 = 0 and n2 = 1 or n1 = 1 and n2 = 0, and; m represents 1 or 2.

    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: The invention relates to a method for producing graft copolymers, containing an elastic copolymer backbone. In a first stage of said method, a) ethene, as the principal monomer, is copolymerised co-ordinatively with an alpha -olefin which is substituted with an alkoxyamine group as the additional comonomer in the presence of a transition metal compound which has been complexed using a bisimin chelate ligand, into an elastomeric graft copolymer backbone. In a second stage b) the copolymer produced in a) is reacted under controlled radical polymerisation conditions in the presence of monomers, selected from the group of vinyl aromatic compounds, vinyl heteroaromatic or vinyl heteroalicyclic compounds, alkyl esters, and amides of (meth)acryl acid, acryl nitrile, methacryl nitrile, maleimide or vinyl ferrocene and optionally also reacted in the presence of conjugated organic dienes, involving the formation of covalently linked graft branches. In a further stage c) the graft copolymer obtained in b) is either directly isolated, or the alkoxyamine groups which terminate the graft polymer lateral branches are first removed under reductive reaction conditions and the graft polymer thus obtained is subsequently isolated.
