PROBLEM TO BE SOLVED: To provide polymeric compositions suitable for molding soft-touch feel articles excellent in surface appearance, low gloss, surface durability etc.SOLUTION: A polymeric composition comprises a blend of: (a) a first polymeric component of a propylene homopolymer and/or an impact resistant polypropylene copolymer; (b) a second polymeric component of a propylene elastomer and/or a linear ethylene polymer; and (c) glass fibers and a grafted polypropylene coupling agent. The polymeric composition is suitable for molding an article that has a soft touch feel, low-gloss appearance, and high surface durability. 【課題】表面外観、低光沢性、表面耐久性などに優れた、ソフトタッチ感触の物品の成形に適したポリマー組成物の提供。【解決手段】（ａ）プロピレンホモポリマー及び／又は耐衝撃性ポリプロピレンコポリマーの第１のポリマー成分；（ｂ）プロピレンエラストマー及び／又は線状のエチレンポリマーの第２のポリマー成分；（ｃ）ガラス繊維並びにグラフト化ポリプロピレンカップリング剤のブレンドを含んでなり、ソフトタッチな感触、低光沢性外観、高い表面耐久性の物品の成形に適したポリマー組成物。【選択図】なし
