    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.
