Polylactic Acid and Poly(Butylene Adipate-Co-Terephthalate) Blends Plasticised with Lactic Oligomers and Epoxy Reactive Plasticizers

Polylactic acid (PLA) is a compostable and sustainable polymer, derived from renewable resources, with high elastic modulus and high transparency. By the way PLA has even some limitations such as low glass transition temperature, low thermal stability, high brittleness, and low crystallization rate....
