The present invention relates to a polypropylene composition comprising a branched polypropylene (b-PP) having high melt strength (HMS). Furthermore, the present invention also relates to a method for providing the corresponding polypropylene having composition comprising the branched polypropylene (b-PP) and to a foam with the polypropylene composition comprising the branched polypropylene (b
THERMAL ANALYSIS OF POLYPROPYLENE-b-POLYETHYLENE …
Difference in thermal behavior of presumed polypropylene-b-polyethylene block copolymers(PP-PE) and corresponding PP+PE blends was studied. Different views in the literature were unified in our observation that faster cooling rate yielded only one exothermal peak for the blends, while slower cooling rates revealed both PP and PE exothermal peaks.
