<p>A composite porous membrane is provided which comprises a porous membrane substrate having an average pore size between 0.01 and 10 microns formed of a first polymer which is coated over its entire surface with a crosslinked second polymer. The second polymer is dissolved in a solvent with a free radical polymerization initiator in the absence of a crosslinking agent. The second polymer is crosslinked in situ and rendered insoluble by mild heating and/or exposure to ultraviolet light.</p> |
