Specifically, the present invention relates to a resin composition that can be used for automobile interior and exterior applications, household electrical appliances, building materials, agricultural films, and the like.

(E-6)充填剤としては、例えば、ガラス繊維、タルク、シリカ、炭酸カルシウム、チタン酸カリウム、ホウ酸カリウムなどが挙げられる。充填剤は必要に応じて、樹脂との親和性を改善するためにチタン系等の表面処理剤で表面処理して用いることが好ましい。また、無機物が球状物の場合は粒径、繊維状物の場合は繊維径や繊維長およびアスペクト比を適宜選択して用いられる。充填剤を配合したポリオレフィン系樹脂は充填剤により直接樹脂の劣化が加速されたり、他の添加剤の効果が損なわれることで耐候性が低くなるため特に高度の耐候性付与技術が必要であり、本発明は充填剤配合ポリオレフィン樹脂組成物において有効である。
