Abstract

The present invention relates to a polypropylene composition showing a high melt flow rate and high melt strength while maintaining high impact strength. The composition of the present invention is obtainable by using a low molecular weight linear isotactic polypropylene as melt flow enhancer for a high molecular weight polypropylene having a high melt strength and impact strength. The inventive composition could be used for the production of different articles.
