Poly (butylene succinate)(PBS)/Calcium carbonate (CaCO 3 ) composite were prepared by melt blending, and studied the effect of different coupling agents, PBS and CaCO3 mass ratio and coupling agent for composite. The results showed that aluminum acid coupling agent for the properties of composite materials improved the most obviously effect; with CaCO 3 content increased, the degradation properties and tensile strength of composite materials rose, the impact strength and elongation at break decreased. With aluminum acid content increased, the tensile propeties and impact strength increased and then stabilization but no influence on degradation. When the PBS and CaCO 3 mass ratio was 7:3, the coupling agent in an amount of 1.5%, the performance of PBS/CaCO 3 composite was better, meeting the basic requirements. Compared with pure PBS, it reduced the cost of nearly 30%, and application further.
