Zusammenfassung:To provide a polyolefin resin composition that has original mechanical properties of resin, has high antistatic performance, and features long-lasting and wiping-resistant of antistatic performance, and an automobile interior material including the same.SOLUTION: A polyolefin resin composition contains a polyolefin resin (F) of 50 to 90 pts.mass, a thermoplastic elastomer (G) of 3 to 40 pts.mass, and a filler (H) of 3 to 30 pts.mass (where, the total of the polyolefin resin, thermoplastic elastomer and filler is 100 pts.mass), and contains at least one polymer compound (E) of 3 to 40 pts.mass based on 100 pts.mass of the total of the polyolefin resin, thermoplastic elastomer and filler. The polymer compound (E) is at least one of polymer compounds obtained by a reaction of a polyester (a) that is obtained by a reaction of diol (a1) and dicarboxylic acid (a2), a compound (b) having at least one ethyleneoxy group and having hydroxy groups at both terminals, and an epoxy compound (D) having at least two epoxy groups. The diol (a1) is at least one of 1,4-butanediol and ethylene glycol. The dicarboxylic acid (a2) is a mixture of succinic acid or succinic acid-containing dicarboxylic acid.SELECTED DRAWING: None 【課題】樹脂本来の力学特性を有し、帯電防止性能が高く、帯電防止性能の持続性および帯電防止性能の耐拭き取り性に優れたポリオレフィン系樹脂組成物、及びそれを用いた自動車内装材を提供すること。【解決手段】ポリオレフィン樹脂(F)を50〜90質量部、熱可塑性エラストマー(G)を3〜40質量部、および、充填剤(H)を3〜30質量部含有するとともに(但し、ポリオレフィン樹脂、熱可塑性エラストマーおよび充填剤の合計は100質量部)、1種以上の高分子化合物(E)を、前記ポリオレフィン樹脂、前記熱可塑性エラストマーおよび前記充填剤の合計100質量部に対して3〜40質量部含有し、前記高分子化合物(E)が、ジオール(a1)とジカルボン酸(a2)が反応して得られるポリエステル(a)と、エチレンオキシ基を一つ以上有する両末端に水酸基を有する化合物(b)と、エポキシ基を2個以上有するエポキシ化合物(D)と、が反応して得られる高分子化合物の1種以上であって、前記ジオール(a1)が、1,4−ブタンジオール、またはエチレングリコールの少なくとも一方であり、前記ジカルボン酸(a2)が、コハク酸、またはコハク酸を含有するジカルボン酸の混合物である、ポリオレフィン系樹脂組成物。【選択図】なし
