본 발명은 a) 융점 Tm을 갖는 하나 이상의 플루오로중합체를 제공하는 단계로서, 상기 하나 이상의 플루오로중합체는, (i) 중합체의 반복 단위들의 총수에 대해 30 몰% 초과의, VDF로부터 유도되는 반복 단위를 포함하고; (ii) 사슬당 0.1 내지 0.9의 양의 요오드-함유 사슬 말단 -CH2I를 갖는 것을 특징으로 하는, 단계; b) 적합한 용매 중에 상기 플루오로중합체를 용해시켜 전구체 용액을 형성하는 단계; c) 상기 전구체 용액으로부터 상기 플루오로중합체를 고체로서 침전시켜, 상기 플루오로중합체를 포함하는 형상화된 물품을 수득하는 단계; e) 상기 형상화된 물품을 100℃ 내지 상기 하나 이상의 플루오로중합체의 최저 융점 Tm 사이의 온도에서 적어도 15분 동안 열처리하여 상기 보강된 형상화된 물품을 수득하는 단계를 포함하는 보강된 형상화된 물품의 제조 방법에 관한 것이다. 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.
