Foamable fluoropolymer compositions

Abstract

本发明涉及可发泡热塑性氟聚合物组合物,包括-至少一种氟聚合物[聚合物(A)];以及-至少一种具有以下任一化学式的全氟烷氧基磺酸衍生物:(Xn+)1/n-O3S-CF2CF2O-Rdf-OCF2CF2-SO3-(Xn+)1/n以及Rmf-OCF2CF2-SO3-(Xn+)1/n,其中Rdf是二价C1-C12的全氟化碳基团,可能包括一个或多个醚氧原子;Rmf是一价C1-C12的全氟化碳基团,可能包括一个或多个醚氧原子,任选地包括杂原子,这些杂原子通常选自S、N、P;X=H、一个金属阳离子或铵基;n是该阳离子X的化合价,优选1或2。
The invention pertains to foamable thermoplastic fluoropolymer composition comprising: - at least one fluoropolymer [polymer (A)]; and - at least one perfluoroalkoxysulphonic derivative of either of formulae: (Xn+)1/n -O3S-CF2CF2O-Rd f-OCF2CF2-SO3-(Xn+)1/n and Rm f-OCF2CF2-SO3-(Xn+)1/n wherein Rd f is a divalent C1-C12 perfluorocarbon group, possibly comprising one or more ethereal oxygen atom;Rmf is a monovalent C1-C12 perfluorocarbon group, possibly comprising one or more ethereal oxygen atom, optionally comprising heteroatoms, generally selected from S, N, P; X = H, a metal cation, or an ammonium group; n is the valence of the cation X, preferably 1 or 2.
