  • Patent number: 7683145
    Abstract: A method for the emulsion polymerization of one or more olefins by reacting a ligand of general formulae Ia and Ib or a mixture of at least two ligands Ia or Ib, wherein R respectively represents one or several of the following radicals; hydrogen, halogen, nitrile, C1-C12-alkyl groups, C1-C12-alkoxy groups, C7-C13-aralkyl groups, C6-C14-aryl groups, and wherein identical or different compounds of general formulae Ia and Ib can, optionally, be concatenated by one or several bridges, with a phosphine compound PR3? and a metal compound of general formula M(L2)2 or M(L2)2 (L1)z, wherein the variables are defined as follows: M is a transition metal of groups 7-10 in the periodic system of the elements; L1 represents phosphanes (R5)xPH3-x or amines (R5)xNH3-x with identical or different radicals R5, ether (R5)2O, H2O, alkohols (R5)OH, pyridine, pyridine derivatives of formula C5H5-x(R5)xN, CO, C1-C12-alkylnitriles, C6-C14-arylnitriles or ethylenically unsaturated double bond systems, wherein x is a whole number ran

  • Patent number: 7566760
    Abstract: The invention relates to a method for the production of aqueous polymer dispersions, by the polymerisation of one or more olefins in aqueous media in the presence of dispersing agents and optionally organic solvents, characterised in that the polymerisation of the olefin(s) is catalysed by means of one or more complex compounds of general formula (I), where at least one of the groups R1 to R9 must be in the form of a group of the following general formula (II) where Z=an electron-withdrawing group and n=a whole number from 1 to 5.

  • Patent number: 7129292
    Abstract: A process for emulsion polymerizing one or more olefins involves reacting it/them with at least one complex compound of the formula Ia or b where M is a transition metal from groups 7 to 10 of the Periodic Table of the Elements and is preferably Ni in aqueous dispersion and at least one radical R1 to R3 and optionally one radical R4 to R9 contains a hydrophilic group X, selection being made from —SO3?, —O—PO32?, NH(R15)2+, N(R15)3+ or —(OCH2CH2)nOH, where n is an integer between 1 and 15. For the process of the invention it is optional to use an activator such as, for example, olefin complexes of rhodium or of nickel.
