摘要: The pyrolysis kinetics of polyurethanes synthesized from polycaprolactone diol (PCL) and diisocyanate (HDI, H12MDI) using catalysts such as dibutyltin dilaurate (DBTDL) were studied by a thermogravimetric (TG) technique, which involved heating the sample at rates 10, 20 30 °C/min. effect kind hard segment contents on activation energy reaction order examined conversions ranging 1 to 100%. energies first increased slowly with increasing conversion. Also, differential scanning calorimetry (DSC) was used investigate structural differences in each polyurethane. DSC can reveal melting behavior, terms glass transition temperature (T g ), is known vary function stoichiometry processing conditions.
