Thermal Properties of Biodegradable Polymers

摘要

Thermal properties of the prepared saccharide-and lignin-based polyurethanes (PU's), and polycaprolactones (PCL's) were studied by differential scanning calorimetry (DSC), thermogravimetry (TG) and TG-Fourier transform infrared spectroscopy (FTIF). Glass transition temperatures (Tg's), cold-crystallization temperatures (Tcc'S) and/or melting temperatures (Tm's) of saccharide-and lignin-based PU's and PCL's were determined by DSC, and phase diagrams were obtained.
