Abstract
The carboxylate induced degradation of the poly[(R,S)-3-hydroxybutyrate](PHB) has been investigated with non-isothermal measurements. The apparent activation energies for PHB degradation have been determined. Application of the Kissinger’s and Flynn-Wall-Ozawa’s method for TG and DSC derived data gave good correlation of the results proving applicability of the non-isothermal DSC measurements for the study. Moreover, dependence of the apparent activation energies on the activity of the carboxylate has been found.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
