Abstract： |
A hollow-fibre ultrafiltration membrane able to resist high temp, solvent, acid, alkali and oxidizing is prepared from the polyarylether sulfone (PES-C) or polyarylether ketone (PEK-C) containing the phenolphthalein as side radial. Its shaping process and technological conditions are also disclosed. |
