Abstract
The present invention relates to a heterophasic polypropylene resin comprising a crystalline propylene homopolymer matrix (A) and an amorphous propylene copolymer phase (B) dispersed within the matrix having excellent mechanical properties, in particular at low temperatures, and at the same time high flowability. Further, the invention relates to a production process of the heterophasic polypropylene resin, the use of such a resin in a polypropylene composition and to articles made of the heterophasic polypropylene resin.
