[0068] According to a first embodiment of the present invention, the surfactant (F) may be a cyclic fluorine compound having the formula (II):

[0069]

[0070] where X 1 , X 2 and X 3 the same or different from each other, independently selected from H, F and C optionally containing one or more chain or non-chain oxygen atoms 1 -C 6 (per)fluoroalkyl group, L is a bond or divalent group, R F is a divalent fluorinated C 1 -C 3 bridging group, and Y is an anionic functional group.

[0071] In formula (II), the anionic functional group Y is preferably selected from the group consisting of those having the formula:

[0072]

[0073] where X a is H, a monovalent metal (preferably an alkali metal) or has the formula -N(R' n ) 4 the ammonium group, where R' n The same or different at each occurrence, a hydrogen atom or a C 1 -C 6 Hydrocarbyl (preferably alkyl).

[0074] Most preferably, the anionic functional group Y is a carboxylate group of formula (3") as defin...

Abstract

The present invention relates to a ferroelectric fluoropolymer, to a method for producing said fluoropolymer and to the use of said fluoropolymer in electrical and / or electronic applications.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to European Application No. 17175933.5, filed on June 14, 2017, the entire content of which is hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a ferroelectric fluoropolymer, to a method for producing said fluoropolymer and to the use of said fluoropolymer in electrical and / or electronic applications. Background technique [0004] Vinylidene fluoride (VDF) copolymers containing repeating units derived from trifluoroethylene (TrFE) are attractive ferroelectric, piezoelectric, pyroelectric, ferrorelaxors due to their ease of processing, chemical inertness and attractiveness and dielectric properties, have been widely used in the manufacture of both electrical and electronic devices. [0005] In particular, vinylidene fluoride (VDF) ternary containing repeating units derived from trifluoroethylene (TrFE) as well as chlorotrifluoro...
