Abstract: A copolymer having amphiphilic blocks includes at least one first hydrophilic block, obtainable from n-butyl acrylate and hydroxyethyl methacrylate monomers, and a second hydrophobic block likely to be obtained from a methyl methacrylate monomer. The copolymer is found to be particularly advantageous for use as an additive for manufacturing a polymer filtration membrane, particularly a PVDF membrane, particularly via a phase inversion method.

Abstract: A web of impregnated fibrous material(s) including N individual tapes of fibrous material(s) stacked and/or joined in relation to one another, in which said N tapes adhere to each other and can overlap at least partially. The tapes of fibrous material(s) include continuous fibers impregnated with at least one thermoplastic polymer, and optionally a chain extender. The web has a surface, in cross-section perpendicular to the axis of the fibers, S, that is substantially equal to the sum of the surface, in cross-section perpendicular to the axis of the fibers, of each initial individual tape, denoted Sth, Sth being equal to N×l×Ep, wherein l represents the average width of a tape and Ep represents the average thickness of a tape, N being between 2 and 2000, and the average thickness of each individual tape being less than or equal to 150 μm.
