Hydrophilic porous membrane.

摘要

A hydrophilic porous membrane comprises a porous membrane made of a hydrphobic polymer and a coating formed on at least one surface of the porous membrane and on the inner surface of pores of the membrane with a water-insoluble hydrophilic polymer soluble in a solvent exhibiting satifactory stability and a satisfactory wetting property with respect to the hydrophobic polymer.
