摘要

Process for providing a polypropylene composition comprising a branched polypropylene in which a polypropylene with a melt flow rate MFR (230°C) of more than 1.0g/10min is reacted with a thermally decomposing free radical forming agent and optionally with a bifunctionally unsaturated monomer obtaining thereby the branched polypropylene wherein the polypropylene composition has a F melt strength of more than 5.8cN and a v melt extensibility of more than 200 mm/s.
