摘要：

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.
