    Abstract: A method for the production of carbon monoxide/olefin copolymers in aqueous media in presence of metal complex catalysts, dispersants and optionally organic hydroxy compounds, in which copolymerization is also carried out in presence of water-soluble macromolecular compounds with a hydrophobic cavity and a hydrophilic envelope. A method for the production of copolymers of carbon monoxide and 2-20C olefinically-unsaturated compounds (CO/olefin copolymers) involves copolymerization in aqueous media in presence of: (a) metal complexes of formula (I); (b) a dispersant; (c) optionally an organic hydroxy compound; and (d) a water-soluble, macromolecular host compound with a hydrophobic cavity and a hydrophilic shell G = 5-, 6- or 7-membered carbocyclic ring system (optionally with heteroatom(s)), -(CRb2)r-, -(CRb2)s-Si(Ra)2-(CRb2)t-, -A-O-B- or -A-Z(R )-B-; R = H, 1-20C alkyl, 3-14C cycloalkyl, 6-14C aryl or (1-20C alkyl)-(6-14C aryl) (all optionally substituted with atoms of Group IVA, VA, VIA or VIIA elements), -N(Rb)2, -Si(Rc)3 or a group of formula (II); q = 0-20; A, B = -(CRb2)r'-, -(CRb)2)s-Si(Ra)2-(CRb2)t-, -N(Rb)- or a ring-system component with r', s or t atoms, or combined with Z to form a ring-component with (r'+1), (s+1) or (t+1) atoms; Ra, Rc = optionally substituted 1-20C alkyl, 3-14C cycloalkyl, 6-14C aryl or (1-20C alkyl)-(6-14C aryl); Rb = H, -Si(Rc)3 or groups as listed for Ra/Rc; r = 1, 2, 3 or 4; r' = 1 or 2; s, t = 0, 1 or 2; (s+t) = 1-3; Z, E , E = a non-metallic Group VA element; M = a Group VIIIB, IB or IIB metal; R -R = hydrocarbyl groups as listed above (e.g. for Ra), with the proviso that at least one of these groups contains hydroxy, amino or acid group(s) or an ionic functional group; L , L = formally charged or neutral ligands; X = a formally mono- or multi-valent anion; p, m, n = 0-4; p = m x n Independent claims are included for: (1) a method for the production of CO/olefin copolymers by copolymerization in aqueous media in presence of (a1.1) a Group VIIIB, IB or IBB metal in the form of a salt or complex salt, (a1.2) a chelate ligand of formula (R )(R )E -G-E )(R ) (III) and components (b), (c) and (d) as above; (2) aqueous copolymer systems obtained by these methods.

    Abstract: The invention relates to a method for the emulsion polymerization of one or more olefins by reacting a ligand according to the general formulae (Ia) to (Ic) or a mixture of at least two of the ligands (Ia) to (Ic), wherein M is a metal of the first group of the periodic table of elements or hydrogen, with a metal compound of the general formula (M(L )2 or M(L )2(L )z, wherein M is a transition metal of the 7 to 10 group of the periodic table of elements and preferably nickel, and immediately using the reaction product for the polymerization or copolymerization of olefins in water or in a solvent mixture that contains at least 50 % by volume of water, optionally in the presence of an activator and an emulsifier. The aqueous dispersions of polyolefins such as polyethylene and ethylene copolymerizates obtained according to the inventive method are suitable for applications in the paper industry such as paper coating or surface sizing, paint coatings, raw materials for adhesives, molded foams such as mattresses, textile or leather applications, carpet backings or pharmaceutical applications.

    Abstract: Metallocene complexes of metals of the 4th, 5th or 6th subgroup of the periodic table of elements, whereby at least one substituted or unsubstituted cyclopentadienyl radical is linked to an element from group III of the periodic system of elements. Said element from group III of the periodic system of elements is a component in a binding link between the cyclopentadienyl radical and the metal ion, carrying a nitrogenxide, phosphorous or sulphur organic group as the only other substituent.
