Separation membrane for use in treatment of liquid comprising aromatic ether polymer hydrophilized with hydrophilizing agent |
摘要 |
[Problems] To provide a novel hydrophilized separation membrane for use in the treatment of a liquid, which comprises an aromatic ether polymer, is less likely to be degraded by sterilization with a high energy ray and has a controlled pore size and a high water permeability. [Means for Solving Problems] A porous separation membrane for use in the treatment of a liquid which is produced by a wet film formation process using an aromatic ether polymer and a hydrophilizing agent. The separation membrane can be used for medical purposes or in a pharmaceutical of food. |
