  • Organic solution of dialkyl peroxydicarbonate, process for producing it, preparation of halogenated polymers with the involvement of this solution and halogenated polymers obtained
    Patent number: 6627717
    Abstract: The invention relates to a process for the preparation of an organic solution of dialkyl peroxydicarbonate which is particularly suited for use in the aqueous suspension polymerization of halogenated monomers. The dialkyl peroxydicarbonates are employed in the aqueous suspension polymerization of halogenated monomers in the form of an organic solution in a water-insoluble organic solvent chosen from conventional chain-regulating agents for halogenated polymers.

  • Vinylidene fluoride polymers, process for manufacturing them and use thereof
    Publication number: 20030176608
    Abstract: Vinylidene fluoride polymers, characterized in that they are thermoplastic vinylidene fluoride/chlorotrifluoroethy-lene/hexafluoropropylene terpolymers and in that they contain at least 70% vinylidene fluoride, process for obtaining them and use thereof.

  • Organic solution of dialkyl peroxydicar-bonate, process for producing it, preparation of halogenated polymers with the involvement of this solution and halogenated polymers obtained
    Publication number: 20020019555
    Abstract: The invention relates to a process for the preparation of an organic solution of dialkyl peroxydicarbonate which is particularly suited for use in the aqueous suspension polymerization of halogenated monomers. According to this process, the dialkyl peroxydicarbonate, prepared by the reaction in water of appropriate amounts of alkyl haloformate with an inorganic peroxide, is separated by extraction by means of a water-insoluble organic solvent chosen from conventional chain-regulating agents for halogenated polymers.
