Estudio cinético del efecto de polifenilsulfona sobre el curado de una resina epoxi/amina mediante calorimetría diferencial de barrido convencional y modulada con temperatura: parte II

In this work we studied the effect of the addition of the linear thermoplastic polyphenyl sulfone (PPSU) on the cure kinetics and the thermal properties of a resin based on diglycidyl ether of bisphenol-A (DGEBA), cured with 4,4´-diaminodiphenyl sulfone (DDS). The kinetic study and the characterization process have been carried out by using differential scanning calorimetry, DSC, and temperature modulated DSC (TMDSC), under isothermal and dynamic conditions. The curing kinetics was discussed in the framework of three kinetic models: Kissinger, Flynn-Wall-Ozawa, and the model of reaction of or...
