Abstract: The present disclosure relates to extruder systems and processes thereof. In at least one embodiment, a method of forming a thermoplastic vulcanizate (TPV) composition includes introducing a thermoplastic polymer to an extruder through a feed throat. The elastomeric polymer is introduced to a melt feeder and an elastomeric polymer melt including the elastomeric polymer is formed. The melt feeder is coupled to the extruder. Elastomeric polymer melt from the melt feeder is introduced to the extruder. The thermoplastic polymer and the elastomeric polymer melt are fed separately to the extruder. The thermoplastic polymer and the elastomeric polymer melt in the extruder are mixed with a plurality of intermeshing screws having a plurality of mixing zones.

Abstract: Polymer compositions that include an ethylene-based polymer and a broad molecular weight distribution propylene-based polymer having a melt strength of 20.0 cN to 200.0 cN; and optionally, a propylene-based elastomer are described. The invention also includes articles, such as films, produced from such compositions and methods of making such compositions and methods of improving melt strength.
