Star polylactide and its stereocomplex blends with enhanced heat stability triggered by microwave heating for degradable packaging

Synthesis and chemical structures of StarPDLA

The chemical structures and molecular weight of the samples are characterized¹H-NMR spectra of l-PLLA, P4, and starPDLA are compared in Fig. 2. The signal of P4 was observed at 3.37 ppm (H^a′),…
