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.
