A new type of polymeric adsorbent possessing both high specific surface area and certain polarity was made of chloromethylated cross-linked polystyrene and phenol by Friedel Crafts reaction. Dichloroethane and nitrobenzene were used as mixed solvents and aluminium chloride was used as catalyst. The reaction temperature was kept at 40℃to 125℃. Results showed that the capacities of the resins for adsorbing phenol from waste water were two times as high as that of Amberlite XAD-4 made by the Rohm and Haas Co. in the U.S.A. Besides

its kinetic property and adsorptability were better than that of XAD-4. The adsor-ption capacities of the resins after 50 cycles remain unchanged.
