Abstract (en)
[origin: WO2020128265A1] The invention relates to a copolymer comprising units derived from fluorinated monomers of formula (I): (I) CX1X2=CX3X4, in which X1, X2, X3 and X4 are each independently chosen from H, F and alkyl groups comprising from 1 to 3 carbon atoms which are optionally partially or completely fluorinated, the H and/or F atoms of the fluorinated monomers being partially replaced by photoactive groups of formula -Y-Ar-R, in the copolymer; Y representing an oxygen atom, or an NH group, or a sulphur atom, Ar representing an aryl group, preferably a phenyl group, and R being a monodentate or bidentate group comprising from 1 to 30 carbon atoms. The fluorinated monomers of formula (I) of the copolymer comprise vinylidene fluoride and trifluoroethylene. The present invention also relates to a method for preparing said copolymer, a composition comprising said copolymer, and to a film obtained from said copolymer.
