Biodegradable porous aliphatic poly(butylene succinate-co-ethylene succinate) s(PBES) was prepared through a direct polycondensation method in supercritical carbon dioxide(scCO₂).The effects of reaction pressure,temperatures and duration time of scCO₂ on the foaming behaviors of PBES were investigated.The obtained porous PBES were characterized by scanning electron micrograph(SEM),X-ray diffraction(XRD).The results showed that the porosity can reach over 55% and the diameter of the pores was in the range 50~200 μm.The crystallinity of PBES was decreased after scCO₂ treatment.
