FOAM PRODUCED FROM POLYPROPYLENE WITH LOW GEL CONTENT

摘要

Process for providing a polypropylene composition comprising a branched polypropylene in which a polypropylene with a melt flow rate MFR2 (230°C) of more than 0.5 g/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 F30 melt strength of more than 20.0 cN and a V30 melt extensibility of more than 200 mm/s.
