Summary:PROBLEM TO BE SOLVED: To provide a modifier for polyethylene resin capable of enhancing long term durability and impact resistance.SOLUTION: There is provided a modifier for polyethylene resin containing a following polyethylene component (A) of 30 mass% to 70 mass% and a following polyethylene component (B) of 30 mass% to 70 mass% and satisfying following properties (1) to (3). Polyethylene component (A); polyethylene having property (1): melt flow rate (HLMFR) at a temperature 190°C and a load 21.6 kg of 0.1 g/10 min. or more and less than 5 g/10 min and property (2):density of 0.915 g/cmto 0.945 g/cm. Polyethylene component (B); polyethylene having property (b1): melt flow rate (MFR) at the temperature 190°C and the load 2.16 kg of 10 g/10 min. or more and less than 200 g/10 min. and property (b2): density of 0.960 g/cmto 0.980 g/cm. Property (1): HLMFR is 1 g/10 min. to 20 g/10 min. Property (2): a melt flow rate ratio (HLMFR/MFR) which is a rate of HLMFR to MFR is 20 to 80. Property (3): density is 0.930 g/cmto 0.950 g/cm.SELECTED DRAWING: None 【課題】長期耐久性、及び耐衝撃性を向上できる、ポリエチレン樹脂用改質材の提供。【解決手段】下記ポリエチレン成分（Ａ）を３０質量％以上７０質量％以下、及び下記ポリエチレン成分（Ｂ）３０質量％以上７０質量％以下含有し、下記の特性（１）〜（３）を満足するポリエチレン樹脂用改質材。ポリエチレン成分（Ａ）；特性（ａ１）：温度１９０℃、荷重２１．６Ｋｇにおけるメルトフローレート（ＨＬＭＦＲ）が０．１ｇ／１０分以上５ｇ／１０分未満であり、特性（ａ２）：密度が０．９１５ｇ／ｃｍ３以上０．９４５ｇ／ｃｍ３以下であるポリエチレン。ポリエチレン成分（Ｂ）；特性（ｂ１）：温度１９０℃、荷重２．１６Ｋｇにおけるメルトフローレート（ＭＦＲ）が１０ｇ／１０分以上２００ｇ／１０分未満であり、特性（ｂ２）：密度が０．９６０ｇ／ｃｍ３以上０．９８０ｇ／ｃｍ３以下であるポリエチレン。特性（１）：ＨＬＭＦＲが１ｇ／１０分以上２０ｇ／１０分以下である。特性（２）：ＭＦＲに対するＨＬＭＦＲの比であるメルトフローレート比（ＨＬＭＦＲ／ＭＦＲ）が２０以上８０以下である。特性（３）：密度が０．９３０ｇ／ｃｍ３以上０．９５０ｇ／ｃｍ３以下である。【選択図】なし
