  • Process for manufacturing fluoropolymer membranes
    Patent number: 10688447
    Abstract: The present invention pertains to a process for manufacturing a fluoropolymer membrane, said process comprising the following steps: (i) providing a composition [composition (C)] comprising, preferably consisting of: at least one fluoropolymer [polymer (F)], a water-soluble liquid medium [medium (Mws)] comprising, preferably consisting of at least one solvent selected from the group consisting of diesters of formula (I-de), esteramides of formula (I-ea) and diamides of formula (I-da); R1 (O?)CO-Ade-OC(?O)R2 (I-de) R1O(O?)C-Aea-C(?O)NR3R4 (I-ea) R5R6N(O?)C-Ada-C(?O)NR5R6 (I-da) wherein: R1 and R2, equal to or different from each other, are independently selected from the group consisting of C1-C20 hydrocarbon groups; R3, R4, R5 and R6, equal to or different from each other, are independently selected from the group consisting of hydrogen, C1-C36 hydrocarbon groups, possibly substituted, being understood that R3, R4, R5 and R6 might be part of a cyclic moiety including the nitrogen atom to which they are bound,
