中文摘要	An effective way to improve the thermostability of poly (beta-hydroxybutyrate) (PHB) was developed. Maleic anhydride(MAH) was grafted onto PHB by Co-60 gamma characterize radiation. H-1-NMR, C-13-NMR, TGA, DSC and XRD we re used to characterize the radiated samples. The results of both H-1-NMR and C-13-NMR are consistent with the successful grafting of MAH monomers onto PHB molecules. The TGA measurements demonstrated that the thermal stability of grafted PHB was measurably improved with the introduction of MAH groups. The 5% weight loss temperature of the grafted PHB with a graft degree of 0.52% was enhanced by 36 K. These significant results suggest that wide commercial application of PHB may be possible. The DSC results showed both the melting temperature and crystallization temperature of the grafting products were decreased. Moreover, the crystallinity of the grafted PHB was decreased with the introduction of MAH groups, and the hydrophilic property was improved.
