The invention relates to a poly(arylsulfone), the poly(arylsulfone) having an aryl group grafted with a covalently attached substituent of the Formula (I): The invention also relates to a process for grafting a poly (arylsulfone), in the presence of an enzyme, for the preparation of said grafted poly (arylsulfone). The poly (arylsulfone) according to the invention shows beneficial properties for application in a membrane. The invention therefore further relates to a membrane comprising a poly (arylsulfone) according to the invention, and to the use of a poly (arylsulfone) according to the invention in a separation process. In addition, the invention relates to a polymer blend and a copolymer comprising a grafted poly (arylsulfone) according to the invention, and to a membrane comprising such polymer blend or copolymer. Cette invention concerne une poly(arylsulfone), ladite poly(arylsulfone) portant un groupe aryle greffé avec un substituant lié par covalence de Formule (I): Cette invention concerne également un procédé de greffage d'une poly(arylsulfone), en présence d'une enzyme, pour la préparation de ladite poly(arylsulfone) greffée. La poly(arylsulfone) selon l'invention possède des propriétés bénéfiques applicables à une membrane. Par conséquent, cette invention concerne, en outre, une membrane comprenant une poly(arylsulfone) selon l'invention, et l'utilisation d'une poly(arylsulfone) selon l'invention dans un procédé de séparation. De plus, cette invention concerne un mélange de polymères et un copolymère comprenant une poly(arylsulfone) greffée selon l'invention, et une membrane comprenant ledit mélange de polymères ou copolymère.
