Abstract
The present invention is relative with an organic liquid absorbent resin comprised of a water-insoluble resin to which have been introduced hydrophilic polar groups. This organic liquid absorbent resin is produced on introducing hydrophilic groups to the water-insoluble resin. This organic liquid absorbent resin is inexpensive, high in safety and superior in is performance in absorbing not only hydrophilic solvents but also oleophilic solvents.
