Claim:
1. A method of manufacturing a hydrophilized hollow fiber membrane by a continuous process using an extruder, the method comprising: (i) supplying a polyvinylidene fluoride (PVDF)-based resin, a hydrophilic resin, a thermal curing agent, and a thermal initiator to an extruder; (ii) mixing and melting the supplied materials to a melt by temperature of a cylinder and rotation of a screw of the extruder; (iii) polymerizing the thermal curing agent in the melt, wherein the polymerization begins by initiating the thermal initiator using heat generated from temperature of the cylinder and rotation of the screw; and (iv) extruding and spinning the melt in which the thermal curing agent is being polymerized.
