Abstract
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.
