摘要：
The thermal stability of lignin-hydroxy terminated polybutadiene (HTPB) copolyurethane and HTPB polyurethane has been studied by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and isothermal aging in air at various temperatures. All the results show better thermal stability of lignin-HTPB copolyurethane than that of HTPB polyurethane. The structural changes in the polyurethanes during isothermal heating have also been studied by IR spectroscopy. (C) 2001 Elsevier Science Ltd. All rights reserved.
