摘要： Block copolymer comprising: - at least one block of a polymer comprising at least 50 mole % of recurring units (R1) formed by the polycondensation reaction between at least one aromatic dihalocompound comprising at least two -S(=O) 2 - groups and at least three aromatic rings, and at least one aromatic diol (block (A)), and - at least one block of a polymer comprising at least 50 mole % of recurring units (R2) formed by the polymerization of at least one alkylene oxide (block (B)). Process to synthesize said block copolymer. Polymer composition comprising said block copolymer. Article, in particular membrane, comprising said block copolymer or said polymer composition. Use of said membrane for purifying a liquid or for separating gases.
