Telechelic Polyhydroxyalkanoates/Polyhydroxybutyrates (PHAs/PHBs)

, 2017
Poly(3-hydroxyalkanoate)s, PHAs, are natural polyesters collected as intracellular granules as a result of a metabolic stress upon unbalanced growth, owing to a limited supply of a necessary nutrient and to the presence of an excess of a carbon source [1,2,3,4,5,6,7-8]. PHAs have material properties ranging from rigid and highly crystalline to elastic,
