Aminated polysulfone membrane and process for its preparation
 A new process for preparing a separation membrane from aminated polysulfone resin or blends of aminated polysulfone-blended materials which utilizes an organic additive having a low or negligible water-solubility (instead of conventional water-soluble organics, polymers, or inorganic salts) in the casting solution. The resulting membrane exhibits high water-permeability and is capable of being formed at a high production rate when using a wet casting machine.
