Patent ID: 7067058

Claim:
A process for making a hydrophilic membrane, comprising the acts of: providing a polymeric micronorous membrane; providing an monofunctional acrylate monomer nEGMA, wherein nEGMA comprises OH 2 ═CCH 3 —C(O)—(O—CH 2 —CH 2 ) n+1 —OH and where n is a variable of greater magnitude than one; providing a diacrylate monomer including hydrophilic units; providing an initiator for facilitating polymerization and crosslinking reactions of the acrylate and diacrylate monomers; and exposing the polymeric membrane to the acrylate and diacrylate monomers in the presence of the initiator to actuate polymerization and crosslinking of the acrylate and diacrylate monomers.
