摘要: Energetic thermoplastic polyurethane elastomers (ETPUs) of glycidyl azide polymer (GAP) were synthesized on GAP/poly(caprolactone)(PCL) (100/0, 50/50) as a soft segment and methylenebis(phenylisocyanate) (MDI) extended 1,5-pentanediol hard by solution polymerization in dimethyl formamide (DMF). Differential scanning calorimetry (DSC) thermo gravimetric analysis (TGA) used to examine the thermal decomposition behavior. Kinetic was performed with model fitting model-free method obtain activation energy function extent conversion. ETPU divided into two stages different energies. The first main weight loss step corresponds elimination N2 from -N3 bonds within polymers. GAP GAP/PCL approximately 190 kJ/mol. second coincides skeleton. those showed an increasing trend.
