To provide a polyolefin composition which can reduce an environmental load and can obtain a molded article having excellent mechanical properties.SOLUTION: There is provided a polyolefin composition using modified lignin obtained by acid-catalyzed solvolysis of a wood raw material using a glycol such as polyethylene glycol as a solvent and an olefin-based polymer having a hydroxyl group and a reactive moiety having reactivity. Specifically, there is provided a polyolefin composition which comprises (A) 10 to 60 mass% of glycol lignin and (B) 40 to 90 mass% of an olefin-based polymer, wherein the olefin-based polymer (B) has a hydroxyl group and a reactive moiety having reactivity.SELECTED DRAWING: None 【課題】環境負荷を低減できるとともに、機械的特性に優れた成形体を得ることができるポリオレフィン組成物を提供する。【解決手段】ポリエチレングリコール等のグリコールを溶媒とした木材原料の酸加溶媒分解処理により得られる改質リグニンと、水酸基と反応性を有する反応性部位を備えるオレフィン系重合体とを用いたポリオレフィン組成物。具体的には、（Ａ）グリコールリグニンを１０～６０質量％、（Ｂ）オレフィン系重合体を４０～９０質量％含むポリオレフィン組成物であって、前記（Ｂ）オレフィン系重合体は、水酸基と反応性を有する反応性部位を備えるものである、ポリオレフィン組成物。【選択図】なし
