Three polystyrene (PS)-polyoxyethylene (POE) block copolymers were synthesized: S114 and S123 as copolymers of POE-F'S-POE type, and 561-10 as that of +PS-X-PO& X+ type. Although the copolymers themselves did not remove nonionic surfactant, polyethylene glycol mono-p-nonylphenyl ether (NP, n = lo),
