Abstract
A biodegradable polymer composition includes a biodegradable matrix polymer, and 0.1 to 5 wt. % of a processing aid having a weight average molecular weight of at least 20,000 g/mol. The processing aid is a reaction product of an acrylate monomer and, optionally, at least one copolymerizable monomer. The amount of the acrylate monomer in the processing aid ranges from 50 wt % to 100 wt %, and the amount of the copolymerizable monomer in the processing aid ranges from 0 wt % to 50 wt %. A biodegradable polymer article includes the biodegradable polymer composition. A method includes mixing a biodegradable matrix polymer with 0.1 to 5 wt. % of a processing aid, having a weight average molecular weight of at least 20,000 g/mol above melting temperatures of the biodegradable matrix polymer and the processing aid, to produce a biodegradable polymer composition.
