Zusammenfassung:	PURPOSE:To produce easily a water treatment material having excellent treating power for oil component by melt-extruding a mixture consisting essentially of an org. polymer and an inorg. compd., and pelletizing the porous foam strand obtd. by solidifying the melt-extruded mixture at a low degree of stretching. CONSTITUTION:A mixture which consists essentially of 30-80pts.wt. an org. polymer and 20-70pts. an ionrg. compd. and is added with required amts. of auxiliary components such as a foaming agent, a cationic component or the like is melt-extruded to a strand. The degree of stretching until such strand solidifies is maintained at
