  The invention pertains to a method for manufacturing a sulfone polymer membrane comprising the steps of: (i) preparing a sulfone polymer solution [solution (SP)] comprising: - at least one sulfone polymer [polymer (P)]; a solvent mixture [mixture (M)] comprising: at least one solvent selected from the group consisting of diesters of formula (Ide) and ester-amide of formula (lea), and optionally comprising at least one diamide of formula (Ida): R1-OOC-Ade-COO-R2 (lde); R1-OOC-Aea-CO-NR3R4 (lea); R5R6N-OC-Ada-CO-NR5R6 (lda), 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 and at each occurrence, are independently selected from the group consisting of hydrogen, C1-C36 hydrocarbon groups, possibly substituted, being understood that R3 and R4 might be part of a cyclic moiety including the nitrogen atom to which they are bound, said cyclic moiety being possibly substituted and/or possibly comprising one or more than one additional heteroatom, and mixtures thereof; Ade, Aea, and Ada equal to or different from each other, are independently a linear or branched divalent alkylene group, and optionally dimethylsulfoxide (DMSO); (ii) processing said solution (SP) into a film; (iii) immersing said film in a non-solvent bath.
