Summary:The present invention is directed to a polyethylene-polypropylene composition comprising a blend (A) being a recycled material, said blend comprising polypropylene and polyethylene, and a compatibilizer (B) being a C2C3C4 terpolymer. Further, the present invention is directed to an article comprising said polyethylene-polypropylene composition and a process for preparing said polyethylene-polypropylene composition. The present invention is also directed to the use of a compatibilizer (B) being a C2C3C4 terpolymer for improving the impact- stiffness balance and the morphology of the blend (A). La présente invention concerne une composition de polyéthylène-polypropylène comprenant un mélange (A) qui est un matériau recyclé, ledit mélange comprenant du polypropylène et du polyéthylène, et un agent de compatibilité (B) qui est un terpolymère C2C3C4. La présente invention concerne en outre un article comprenant ladite composition de polyéthylène-polypropylène et un procédé de préparation de cette composition de polyéthylène-polypropylène. La présente invention concerne également l'utilisation d'un agent de compatibilité (B) qui est un terpolymère C2C3C4 permettant d'améliorer l'équilibre entre la résistance au choc et la rigidité ainsi que la morphologie du mélange (A).
