The second degradation rapidly followed and almost showed the same trend as the first degradation: an increase in themal stability and gibbs free energy, but because of the presence of the catalyst Figure (h) and crosslinker Figure (i), which were added manually thus unequal dispersion might be expected, a slight increase of VE_neat in the slope of the line (k), activation energy, ∆S, and ∆H were observed over VE_5% MEPECO. In contrast, residue yield shows a slight decrease in thermal stability, slope of the line, t 1/2 , and gibbs free energy of VE_5% MEPECO compared with VE_neat but a slight advantage in activation energy, ∆S, and ∆H.
