POROUS POLY(CYCLIC OLEFIN) MEMBRANES

The disclosure provides certain porous membranes comprised of cyclic polyolefin polymers, such as poly(norbornene)s. In one embodiment, a poly(norbornene) polymer is dissolved in tetrahydrofuran, cast into a film and subjected to solvent induced phase separation to provide a porous filter membrane (...

More Information
Summary:The disclosure provides certain porous membranes comprised of cyclic polyolefin polymers, such as poly(norbornene)s. In one embodiment, a poly(norbornene) polymer is dissolved in tetrahydrofuran, cast into a film and subjected to solvent induced phase separation to provide a porous filter membrane (i.e., film).
