Sažetak
The thermal degradation of poly(3-hydroxybutyrate)/aliphatic-aromatic copolyester (PHB/AAC) blends was investigated by the thermogravimetric method under dynamic conditions (50-650°C) in an inert atmosphere. The characteristics of the TG curves were determined ; some of these characteristics can be used as indicators of the thermal stability of the blend. Kinetic parameters (the apparent activation energy, Ea and pre-exponential factor, A) were calculated after Flynn-Wall-Ozawa and Kissinger methods. It is observed that both Ea and A vary in blends. Between ln A and Ea exists the linear relationship and the apparent compensation effect has been found.
