“…The current trend toward improving the sustainability of industrially used thermoplasts ,, is challenged by a dilemma to design strong and ductile materials from an intrinsically degradable polymer. On the one hand, the moderate biodegradability of PLA-based products makes its degradation, even in the environment of industrial composting plants, not feasible on a short-term time scale of a few weeks. , On the other hand, the material properties of PLA such as brittleness, − low glass transition temperature ( T g ≈ 55 °C–60 °C), as well as low thermal and hydrolytic stability ,− are not optimal in order to widely replace commodity thermoplastic polymers, e.g., poly(ethylene terephthalate) (PET) …”
