  • Polymerization process
    Patent number: 7645845
    Abstract: A process for producing a polymer by polymerizing at least one fluorinated monomer in the presence of a radical initiator and a surfactant in a polymerization medium containing essentially only carbon dioxide. The surfactant is a functional (per)fluoropolyether having recurring units (R1) and at least one functional group containing a heteroatom other than fluorine, the recurring units containing at least one ether linkage in the main chain and at least one fluorine atom. Molded article containing the polymer obtained from the process.
    Type: Grant

  • Polymerization process
    Publication number: 20070015888
    Abstract: The invention pertains to a polymerization process including polymerizing at least one fluorinated monomer in the presence of a radical initiator and a surfactant in a polymerization medium containing carbon dioxide to provide a polymer product, characterized in that the surfactant is a functional (per)fluoropolyether, which is a polymer comprising recurring units (R1) and at least one functional group having a heteroatom other than fluorine, said recurring units having at least one ether linkage in the main chain and at least one fluorine atom (fluoropolyoxyalkene chain).
