Disclosed are propylene compositions comprising a propylene polymer, a substantially linear ethylene polymer, linear ethylene polymer or combinations thereof, a low molecular weight polymer and optionally a filler. Said propylene polymer compositions have improved processability with a good balance of stiffness and toughness and demonstrate improved scratch resistance in injection molded articles.

L'invention concerne des compositions polymères de propylène contenant un polymère de propylène, un polymère d'éthylène pratiquement linéaire, un polymère d'éthylène linéaire ou des mélanges associés, un polymère à faible poids moléculaire et, facultativement, une charge. Lesdites compositions polymères de propylène présentent une aptitude au traitement accrue parallèlement à un bon équilibre de rigidité et de dureté, ainsi qu'une résistance améliorée aux égratignures dans des articles moulés par injection.
