Abstract
A hydrophilic porous membrane is provided which comprises a network of a non-crystalline hydrophobic polymer and an in situ crosslinked 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 polyfunctional acrylate, a polymerization initiator, and, optionally, a monofunctional monomer, is polymerized in situ and cast to provide a hydrophilic porous membrane.
