Enhanced heat stability polypropylene

A process forming a high MFR polypropylene includes providing a reactor powder polypropylene, the reactor powder polypropylene having a melt flow rate of less than 100 dg/min. The process also includes mixing the reactor powder polypropylene with a free-radical initiator to form a powder/initiator m...

Beschreibung
Zusammenfassung:	A process forming a high MFR polypropylene includes providing a reactor powder polypropylene, the reactor powder polypropylene having a melt flow rate of less than 100 dg/min. The process also includes mixing the reactor powder polypropylene with a free-radical initiator to form a powder/initiator mixture and subjecting the powder/initiator mixture to post-reactor forming. The present disclosure further provides for a vis-broken polypropylene and a polymer article.
