Abstract

Provided herein are polymer compositions comprising a polymer and polyethylene glycol (PEG)-based polymer processing aid (PPA). The polyethylene glycol can have molecular weight less than 40,000 g/mol. The polymer can be a C-Colefin homopolymer or a copolymer of two or more C-Cα-olefins, and the polymer composition can take the form of polymer pellets; a polymer melt; reactor-grade polymer granules and/or polymer slurries; or other form of polymer composition containing the PPA and optionally one or more other additives. The polymer composition is preferably free or substantially free of fluorine, including fluoropolymer-based PPAs.
