Abstract

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).
