Zusammenfassung:	To provide a method for producing an olefinic polymer which shows almost no influence on olefinic polymerization activity of a metallocene catalyst and the like even if using a recovered polymerization solvent which has been used for olefinic slurry polymerization.SOLUTION: The present invention discloses a method for producing an olefinic polymer. In the presence of a metallocene catalyst, olefinic polymerization is performed which uses, as a polymerization solvent, the polymerization solvent that has been used in the olefinic polymerization reaction and then brought into contact with at least one high silica zeolite selected from the group consisting of hydrogen cationic beta zeolite, hydrogen cationic ZSM-5 zeolite and hydrogen cationic Y-type zeolite.SELECTED DRAWING: None 【課題】オレフィンのスラリー重合に使用した回収重合溶媒を用いても、メタロセン系触媒のオレフィン重合活性等にほぼ影響の観測されないオレフィン重合体の製造方法を提供する。【解決手段】メタロセン系触媒の存在下、オレフィンの重合を行う際に、重合溶媒としてオレフィン重合反応後の重合溶媒を水素陽イオン型ベータ型ゼオライト、水素陽イオン型ＺＳＭ－５型ゼオライト及び水素陽イオン型Ｙ型ゼオライトからなる群より選択される少なくとも１種のハイシリカゼオライトで接触処理した重合溶媒を用いることを特徴とするオレフィン重合体の製造方法。【選択図】なし
