Beschreibung
Zusammenfassung:	The present invention pertains to a method for making a reinforced shaped article comprising the steps of: a) providing one or more fluoropolymers having a melting point Tm, said one or more fluoropolymers being characterized in that they: (i) comprise more than 30% by moles of recurring units derived from VDF, with respect to the total number of recurring units of the polymer; (ii) have iodine-containing chain ends -CH2I in an amount of 0.1 to 0.9 per chain; b) dissolving said fluoropolymer in a suitable solvent and forming a precursor solution c) precipitating said fluoropolymer as a solid from said precursor solution thereby obtaining a shaped article comprising said fluoropolymer e) thermally treating said shaped article for at least 15 minutes at a temperature comprised between 100° C. and the lowest melting point Tm of said one or more fluoropolymers thereby obtaining said reinforced shaped article.
