ABSTRACT:
A process for production of a partially hydrophilized absorbent is described, which comprises using, as a starting material, porous particles made of an organic compound having properties such that they are shrunk in a solvent containing water as a major component and swollen in a solvent containing an organic solvent as a major component; newly introducing functional groups to react with any one compound selected from the group consisting of compounds containing hydroxyl, amino, carboxyl, halogen or epoxy group in a solvent containing an organic solvent as a major component; and then reacting with a compound containing alcoholic OH group in a solvent containing water as a major component to immobilize the compound containing alcoholic OH group on the outer surfaces of the particles.
