Glycerol-based additives of poly(3-hydroxybutyrate) films

Glycerol (G), polyglycerols (PGs), glycerol triacetate (GTA), and glycerol tributyrate (GTB) were studied as additives of poly(3-hydroxybutyrate) (PHB). The effect of different concentrations (5–30%) of these compounds on microstructure and final properties of PHB films were evaluated. Microscopic s...
