Abstract
A hydrophilic porous membrane is provided which comprises a network of a non-crystalline hydrophobic polymer and a hydrophilic acrylate polymer. A method of preparing such a hydrophilic porous membrane also is provided, wherein a reaction solution of a non-crystalline hydrophobic polymer, a crosslinkable diacrylate, a polymerization initiator, and, optionally, a hydrophilic monoacrylate, is polymerized and/or crosslinked in situ and cast to provide a hydrophilic porous membrane.
