The present invention relates to a fluorine-containing alternating copolymer macromonomer and a synthesis method thereof. The synthesis method comprises steps of: subjecting a fluorine-containing alternating copolymer to a reduction reaction at 60-100° C. in an organic solvent in the presence of a reducing agent and a first catalyst to obtain a reduction product; in the presence of a second catalyst, reacting the reduction product with a mercapto-monohydric alcohol in an organic solvent at 60-100° C., to obtain a hydroxyl-terminated fluorine-containing alternating copolymer; and in the presence of a third catalyst, reacting the hydroxyl-terminated fluorine-containing alternating copolymer with an acrylic monomer or acryloyl chloride monomer at 0-30° C., to obtain the fluorine-containing alternating copolymer macromonomer. In the present invention, a fluorine-containing alternating copolymer macromonomer is initially synthesized from a fluorine-containing alternating copolymer through polymer modification.

The invention pertains to a thermoplastic fluoropolymer composition comprising one or more polymer A comprising recurring units derived from ethylene and recurring units derived from halogenated monomers selected from chlorotrifluoroethylene (CTFE) and tetrafluoroethylene (TFE) and one or more polymer B comprising recurring units derived from ethylene, recurring units derived from halogenated monomers selected from CTFE and TFE, and recurring units derived from hexafluoroisobutylene (HFIB) and/or perfluoropropylvinylether (PPVE). The resulting composition allows to manufacture films having exceptional transparency and good mechanical properties which can be used for examples as architectural films.

Provided is a high oil contact angle coating comprising fluoropolymer, compositions and processes for forming the coating, and articles comprising the coating. The fluoropolymer is a crosslinkable tetrapolymer fluoropolymer produced from the copolymerization of monomers tetrafluoroethylene, fluoro(alkyl vinyl ether) or fluoro(alkyl ethylene), alkyl vinyl ether and alkenyl silane. The fluoropolymer coating has high oil contact angle and utility as coating when the fluoropolymer is in the uncrosslinked or crosslinked state.
