Abstract
A hydrophilized membrane of a porous hydrophobic material having micropores each defined by a surface at least part of which is coated with a hydrophilizing agent which is solid at about 20.degree. C. and substantially insoluble in water. The hydrophilizing agent is preferably selected from monofatty acid esters of propylene glycol. Also disclosed are processes for hydrophilizing such porous hydrophobic membranes.
