Abstract Poly(3-hydroxybutyrate) (PHB) is a biothechnological and biodegradable thermoplastic polymer from the polyhydroxyalkanoates (PHAs) family, whose chain regularity, high molecular weight, and physical and mechanical properties comparable to polypropylene (PP) are characteristics that have made PHB a prominent commercial bioplastic. Nevertheless, its susceptibility to thermal degradation and hydrolysis has limited many applications. To address the challenges associated with processing, a random copolymer of 95.86 mol% 3-hydroxybutyrate and 4.14 mol% 3-hydroxyvalerate (referred as PHB) was compounded without (neat PHB) and with 0.25, 0.5, 1, and 1.5 wt% of chain extender (Joncryl®ADR 4368), consisting of multifunctional epoxy groups, and… More >
