摘　　要：探索用60Coγ射线辐照的方法进行聚β-羟基丁酸酯(PHB)接枝顺丁烯二酸酐(MA)。并通过改变辐照反应条件,如单体浓度、辐照剂量以及辐照剂量率,研究其对接枝产物的接枝率、粘均分子量、热稳定性以及熔融行为的影响。This paper focuses on finding an effective way to improve the thermostability of poly（ β- hydroxybutyrate） （PHB）. Graft polymerizations of maleic anhydride onto poly（ β- hydroxybutyrate） by ^60 Co γ Radiation were carried out with different monomer concentrations, radiation doses and radiation dose rates. Graft degree, viscous average molecular weight, thermostability and melting behaviors of the radiated samples were studied.
