摘要 |
<p>A mixture composed of a surfactant, a hydrophilic polymer which is insoluble to water and alcohol, and a water soluble polymer is retained on the surface of a hydrophobic porous membrane material and/or at inner surface of pores and the surfactant is retained by the hydrophilic polymer. By taking the above constitution, a hydrophilic porous membrane which is restrained in dissolution and generation of foaming and is excellent in safety can be obtained.</p> |
