In this study, plasticization of polylactide (PLA) with PEG–PPG–PEG triblock copolymers was examined. Two different copolymers were utilized, with molecular weight of 1100 and 1900 g mol−1, and with PEG contents of 10 and 50 wt %, respectively. A PPG plasticizer with molecular weight of 1000 g mol−1, close to that of PPG block in the copolymers, was also used for comparison. Melt blends containing...
