摘　　要：采用熔融共混的方法制备聚丁二酸丁二醇酯(PBS)/空心玻璃微珠(HGB)复合材料。考察了HGB对PBS熔融与结晶特性、动态流变行为、应力-应变行为及拉伸性能的影响。结果表明:HGB会促进PBS的结晶,提高结晶度,但对PBS的熔融特性影响较小;填充HGB以后,PBS的弹性模量和抗形变能力增强,拉伸强度和断裂伸长率下降;PBS/HGB复合体系在应力-应变过程中,不存在屈服现象,显示脆性断裂行为。Poly（butylene succinate） （PBS）/hollow glass bead （HGB） composites were prepared by melt blending method. The effect of HGB on the melting and crystallization behavior, dynamic viscoelastic behavior, stress-strain behavior and mechanical properties of PBS were investigated. The results indicate that the HGB increases the crystallization rate and the crystallinity of PBS but it has a little influence on the melting behavior of PBS. The storage modulus and resist elastic deflection of PBS are enhanced with the increase in HGB content, however the tensile strength and elongation at break decrease. In the stress-strain curve of PBS/HGB, there is no yield phenomenon, which shows the brittle fracture behavior.
