Abstract
The present invention provides a shaped permeable polymeric material including a hydrophobic portion and a hydrophilic portion, wherein the material is crosslinked. This material is prepared by a method including the steps preparing a crosslinkable composition having a hydrophobic portion and a hydrophilic portion; placing the crosslinkable composition in a mold; gelling the crosslinkable composition to form a shaped gelled polymeric composition comprising a hydrophobic portion, a hydrophilic portion, and a liquid portion; and exchanging the liquid portion with an exchange liquid to form the permeable polymeric material. Preferably this material is used in a blood gas sensor.
