Disclosed are propylene polymer compositions comprising a high crystalline propylene polymer, a substantially linear ethylene polymer, linear ethylene polymer or combinations thereof, an optional filler and an optional additional polymer. Said propylene polymer compositions have improved processability with a good balance of stiffness and toughness which demonstrates improved scratch resistance in injection molded articles.

L'invention concerne des compositions de polymère de propylène comprenant un polymère de propylène hautement cristallin, un polymère d'éthylène sensiblement linéaire, un polymère d'éthylène linéaire, ou des combinaisons de ceux-ci, une charge optionnelle et un éventuel polymère supplémentaire. Lesdites compositions de polymère de propylène possèdent une plus grande capacité de transformation et un bon équilibre de rigidité et ténacité, se traduisant par une plus grande résistance à la rayure dans les articles moulés par injection.
