PELLETS OF LIGHTLY VIS-BROKEN POLYPROPYLENE

A process including vis-breaking of polypropylene in the presence of 3,6,9-triethyl-3,6,9-trimethyl-1,4,7-triperoxonane to obtain vis-broken polypropylene is provided. The vis-broken polypropylene may be pelletized to obtain pellets. A ratio of a melt flow rate (MI2) of the pellets to a melt flow ra...

Zusammenfassung:A process including vis-breaking of polypropylene in the presence of 3,6,9-triethyl-3,6,9-trimethyl-1,4,7-triperoxonane to obtain vis-broken polypropylene is provided. The vis-broken polypropylene may be pelletized to obtain pellets. A ratio of a melt flow rate (MI2) of the pellets to a melt flow rate (MI2) of the polypropylene prior to the vis-breaking may be greater than 1:1 and at most 4:1. The pellets may be used to form articles.
