Hydrophilic copolymers and membranes |
| abstract |
The present invention relates to a process for the preparation of a polyarylethersulfone-polyalkylene oxide (PPC) block copolymer by conversion of a reaction mixture (RG) which comprises, inter alia, at least one aromatic dihalosulfone, at least one dihydroxy component comprising trimethylhydroquinone and at least one polyalkylene oxide. The present invention further relates to a polyarylethersulfone-polyalkylene oxide (PPC) block copolymer obtainable by the process of the invention as well as its use in a membrane (M) and a membrane (M) comprising the polyarylethersulfone block copolymer Polyalkylene oxide (PPC). In addition, the present invention relates to a method for preparing a membrane (M). |
