Abstract

See full text

Provided herein are polymer compositions comprising a polymer and polymer processing aid (PPA) comprising a blend of at least two of: (i) a polyethylene glycol; (ii) a surfactant comprising a sorbitan ester or a polysorbate; and (iii) a metal salt of a fatty acid. The polymer can be a C2-C6 olefin homopolymer or a copolymer of two or more C2-C20 α-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.
