Thermal, rheological and microstructural characterisation of commercial biodegradable polyesters

Growing environmental concerns along with new regulations are forcing the industries to seek renewable raw materials for their products. In this sense, this work studies the thermo-rheological properties of commercial biodegradable polyesters: two polylactic acids (PLAs), a polycaprolactone (PCL) an...
