Abstract

The thermal stability, crystallization behavior and biodegradability of poly(β-hydroxybutyrate) (PHB) grafted with maleic anhydride (MA) were studied by DSC, TGA, optical microscopy and WAXD. The results showed that thermal stability of maleated PHB was obviously improved, comparing with that of pure PHB. The temperature of decomposition was enhanced about 20°C. After grafting MA, the crystallization behavior of PHB changed evidently. The rate of spherulite growth decreased, the crystallization temperature from the melt state reduced, and the cold crystallization temperature from the glass state increased. With the increase in graft degree, the banding texture of spherulite became more distinct and orderly. Moreover, the introduction of MA groups promoted the biodegradation of PHB.
