A new E1cB mechanism for the thermal degradation of PHB, induced by carboxylate groups has been proposed. The mechanism is considered to be the main PHB degradation pathway operating at moderate temperatures. The results of this work show that thermal stability of PHBs, as well as of their blends, can be controlled by chemical structure and concentration of the carboxylate polymer end groups

The mechanism is considered to be the main PHB degradation pathway operating at moderate temperatures. The results of this work show that thermal stability of PHBs, as well as of their blends, can be controlled by chemical structure and concentration of the carboxylate polymer end groupsFile in questo prodotto:
