Beschreibung
Zusammenfassung:	Disclosed are propylene polymer compositions comprising a propylene polymer, a polyolefin elastomer, a fluoropolymer, and an optional filler. Said propylene polymer compositions have a good balance of stiffness and toughness, especially low temperature toughness, with improved flow marks and/or gloss in injection molded articles. L'invention concerne des compositions de polymère de propylène comprenant un polymère de propylène, un élastomère polyoléfinique, un fluoropolymère et une charge optionnelle. Ces compositions de polymère de propylène présentent un bon équilibre entre rigidité et ténacité, et notamment la ténacité à basse température, ainsi que des lignes d'écoulement et/ou un brillant améliorés dans des articles moulés par injection.
