The kinetic parameters (reaction order, n, activation energy, E, pre-exponential factor, A, constant rate, k) for the dehydration step due to elimination of osmotic water and hydrogen-bounded water with the carboxylic groups, and
for the anhydrifying step owing to the dehydration of two neighboring (-COOH) groups, were determined under non-isothermal
conditions for some carboxylic resins with acrylic-divinylbenzene (DVB) matrix. The kinetic parameters were evaluated by means
of isoconversional methods from (TG/DTG) thermal analysis data. The results show a dependence of the apparent kinetic parameters
on the cross-linking degree, granulation, gel/macroporous matrix nature, exchange capacity and heating rate.
