  • Catalyst systems based on transition metal complexes for carbon monoxide copolymerization in an aqueous medium
    Patent number: 6852662
    Abstract: Catalyst systems for the copolymerization of carbon monoxide and ?-olefinically unsaturated compounds contain, as essential components, a) a metal complex of the formula (I) ?where R1 to R4 are each linear or branched C2- to C28-alkyl, C3- to C14-cycloalkyl or alkylaryl where the alkyl moiety is of 1 to 28 carbon atoms and the aryl moiety is of 6 to 15 carbon atoms, each of which is substituted by at least one polar protic or ionic functional group based on elements of groups IVA to VIA of the Periodic Table of Elements, and b) if required, one or more Lewis or protic acids or a mixture of Lewis and protic acids.

  • Water-soluble transition metal complexes
    Patent number: 6667386
    Abstract: Water-soluble transition metal complexes of the formula (I) where R1 to R4 are linear or branched C2- to C28-alkyl, C3- to C14-cycloalkyl or alkylaryl where the alkyl moiety is of 1 to 28 carbon atoms and the aryl moiety is of 6 to 15 carbon atoms, each of which is substituted by at least one polar protic or ionic functional group based on nonmetallic elements of groups IVA to VIA of the Periodic Table of Elements.
