Study on Properties of Poly(propylene carbonate) /Poly(butylene succinate) Blends

The Poly(propylene carbonate)/poly(butylene succinate) (PPC/PBS) blends were prepared by melt blending, and the effects of addition amount of PBS on the mechanical properties, crystallization, thermal stability of the PPC/PBS blends were studied by mechanical properties testing, DSC and TG. The results show that: the tensile strength, notched impact strength and thermal stability of the PPC/PBS composites improve with the addition of PBS.
