Abstract of the Disclosure The present invention discloses a hydrophilized porous membrane with a crosslinked hydrophilic polymer, which is composed principally of diacetone acrylamide, held physically on at least a part of the pore walls of a starting porous polyolefin membrane, as well as its production process. This hydrophilized porous polyolefin membrane has long-lasting hydrophilicity and good mechanical strength. Its components are dissolved out only minimally in application.
