the chemical cure of phenolic resins [ 9 – 11 ] and tannin-based adhesives [ 12 – 14 ]. In addition, isoconversional methods [ 15 ] have been extensively used to describe complex kinetics of processes which involve multiple steps, as is the case of
, the isoconversional methods are used. Since every isoconversional method has different error, the use of more than one method can give a range of values for the activation energy at every particular value of α. The OFW [ 30 , 31 ] method
curing agent 4,4′-diaminobiphenyl (DABP) system. Thermal kinetics of the system was analyzed based on the isoconversional method and Kamal model. The detailed dynamic mechanical properties and the liquid crystalline transition of DGEBA systems cured with
mechanism, which is expected taking into account the structure of the complex and the nature of the degradation fragments [ 33 ]. In the case of complex processes involving the parallel reactions, as we have here, the isoconversional methods give the
thermal behavior through the TG-DTA and DSC techniques and to obtain the kinetic parameters for the thermal decomposition reaction. Kinetic parameters—non-linear isoconversional method The kinetic parameters for the thermal
provide the kinetic parameters by the Capela-Ribeiro iso-conversional non-isothermal method. Kinetic parameters—non-linear isoconversional method The kinetic parameters for the thermal decomposition step of the compound
method has been declined in favor of isoconversional method of model-free approach [ 39 – 41 ]. All kinetic methods assume that the isothermal rate of conversion, dα/d t , is a linear function of the temperature dependent rate constant, k ( T
) KnowItAll search program and Gases&Vapours Database (code GS) and Organics&Polymers Database (code TU, SR) were used. The differential isoconversional method of Friedman [ 17 ] was applied to calculate the kinetic parameters. After baseline
isoconversional method, namely, Flynn–Wall–Ozawa (F–W–O) method [ 37 , 38 ] that allows for evaluating kinetic parameters without choosing the reaction model was applied. F–W–O is a relatively simple method of determining activation energy directly from mass loss
10% of H40 at different heating rates. As expected, this figure shows how a decrease in the heating rate displaces the curing curves down to lower temperatures. Applying the Ozawa isoconversional method to the thermal curing of the different
