Abstract: 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.

Abstract: A method of forming a thermoformed article may include melt extruding polyethylene to form an extruded sheet. The rheological breadth parameter of the polyethylene may change by no more than about 5% after extrusion relative to the rheological breadth parameter of the polyethylene prior to extrusion. The extruded sheet may be thermoformed within a mold to form the thermoformed article. During thermoforming, the extruded sheet may be subjected to solid-state stretching in one or more directions. The thermoformed article may be retrieved from the mold. The polyethylene may have a rheological breadth parameter of from 0.20 to 0.40, a multimodal molecular weight distribution, a polydispersity (Mw/Mn) of from 5 to 18, a density ranging from 0.940 to 0.970 g/cc, may exhibit tensile strain-hardening, or combinations thereof.
