| Abstract: | 1,6-Bis(hydroxyisopropyl urethane)hexane(BPU) was prepared by non-ioscyanide route from propylene carbonate and 1,6-hexanediamine,whose molecular weight was 320.Blends of biodegradable poly(propylene carbonate)(PPC) and BPU were prepared by melt blending.BPU as modifier to PPC was found to be miscible with PPC,and the thermal properties of the PPC/BPU blends were evaluated by differential scanning calorimetry(DSC) and thermogravimetry analysis(TGA).The thermal stability of the blends was significantly impro... |
