This work concerns the systematic dielectric relaxation spectroscopy (DRS) study of a dynamic network based on the thermoreversible Diels-Alder (DA) reaction of a 4-functional furan-functionalized Jeffamine coupled with a 2-functional maleimide, focussing on the cooperative segmental dynamics as represented by the dielectric -relaxation. In a first step, the VFT parameters describing the relaxation time traces of the -process were derived for each partially cured sample. In a second step, global fits of all DRS spectra were successfully obtained without including effects due to reaction, as well as with, through the introduction of a kinetic model.
