Abstract
The thermal stability of lignin-hydroxy terminated polybutadiene (HTPB) cop olyurethane and HTPB polyurethane has been studied by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and isothermal aging i n air at various temperatures. All the results show better thermal stabilit y of lignin-HTPB copolyurethane than that of HTPB polyurethane. The structu ral changes in the polyurethanes during isothermal heating have also been s tudied by IR spectroscopy. (C) 2001 Elsevier Science Ltd. All rights reserv ed.
