  • Patent number: 11434385
    Abstract: A process for preparing a crosslinked fluoropolymer film, including the successive steps of: (1) formulating an ink containing: (a) the product of the reaction of triethylamine with at least one fluorinated copolymer obtained by radical copolymerization of monomers including: (i) vinylidene fluoride (VDF), (ii) trifluoroethylene (TrFE), (iii) at least one chlorinated monomer of formula —CXCl?CX1X2 where X, X1 and X2 independently denote H, F or CF3, wherein at most one of X, X1 and X2 denotes CF3; (b) at least one crosslinking agent; (c) at least one photoinitiator; and (d) at least one organic solvent; (2) applying said ink in film form to a substrate; and (3) UV-irradiating said film. Also, the film capable of being obtained according to this process, and also to the uses thereof, in particular in the manufacture of (opto)electronic devices and more particularly in the manufacture of a gate dielectric layer in a field-effect transistor.

  • Publication number: 20220251263
    Abstract: The present invention relates to the use of a fluorinated copolymer in the manufacture of a solid polymer film, to give said film properties of adhesion to a metal surface or to glass. It also relates to a process for improving the adhesion of a fluoropolymer to a metal, polymer or glassy substrate, and also to a composite part comprising a solid polymer film in direct contact with at least one metal or glassy element.

  • Patent number: 8197847
    Abstract: The application discloses a process for making a polymer having pendant side groups comprising: (i) polymerising an olefinically unsaturated monomer functionalized with (a) an azide group optionally protected by a protecting group, or (b) an alkyne group optionally protected by a protecting group, by living radical polymerization, most preferably RAFT, transitional metal mediated living radical polymerization (TMM-LRP) and/or atom transfer radical polymerization, to produce a polymer intermediate; (ii) removing, when present, at least a portion of the total number of protecting groups from the polymer intermediate; (iii) reacting the polymer intermediate with at least one pendant side group moiety functionalised with (a) an alkyne group or (b) an azide group respectively so that the alkyne and azide groups react to attach the pendant side group to the polymer. Processes for making supports comprising pendant side groups, and polymers and supports prepared by the method are also disclosed.
