Abstract

Polylactide (PLA) plasticized with poly(ethylene glycol) (PEG) is unstable. In time, some of the PEG exudes to the surface of the composite; some PEG forms separate domains and / or crystals within the PLA; and a fraction of the PEG remains dissolved within the PLA. This disclosure teaches various products that may benefit from the fugitive plasticization of PLA by PEG.
