Recycled Polyethylene-Polypropylene Blend with Compatibilizer

摘要

The present invention relates to a polyethylene-polypropylene composition, said polyethylene-polypropylene composition comprising a blend (A) which is a recycled material, and a compatibilizer (B) which is a copolymer of 1-butene and ethylene, said composition comprising: The blend includes polypropylene and polyethylene. Furthermore, the present invention relates to an article comprising said polyethylene-polypropylene composition and to a method for preparing said polyethylene-polypropylene composition. The present invention also relates to the use of a compatibilizer (B) which is a copolymer of 1-butene and ethylene, said use for improving the impact-stiffness balance and morphology of the blend (A).
