Disclosed is a porous membrane made of an aromatic hydrophobic polymer that provides a water-wettable surface and whose surface wettability is stable over long-term use. A self-wetting porous membrane comprising an aromatic hydrophobic polymer such as polysulfone and a wetting agent comprising a copolymer of formula AB or formula ABAA, wherein A is a polymerized formula (I): a hydrophilic segment comprising monomers of CH2 = C (R1) (R2), wherein R1 and R2 are as described herein and B is an aromatic hydrophobic polymer segment And the segments B and A are linked via an amidoalkylthio group, a self-wetting porous membrane.
