Abstract
Provedena je kinetička analiza izotermne toplinske razgradnje poli(etilen-oksida) različitih molekulnih masa, primjenom eksperimentalnih podataka dobivenih izotermnom termogravimetrijskom analizom. Primjenom integralne “model-free” izokonverzijske metode utvrđeno je da za široko područje konverzija aktivacijska energija (E) ne ovisi o konverziji, što ukazuje na jednostupanjski proces. Kinetički model f( ), aktivacijska energija (E) i predeksponencijalni faktor (A) određeni su za svaki uzorak primjenom krivulja reduciranog vremena (RTP). Točni matematički izrazi kinetičkog modela dobiveni su usuglašavanjem s eksperimentalnim podacima. Kinetička analiza je provedena i primjenom Netzch Thermokinetics programa. Ovako dobiveni kinetički parametri E, A i f(α) se jako dobro podudaraju ranije izračunatim kinetičkim parametrima primjenom “model free” i RTP metode što ukazuje na ispravnost postupka provedene kinetičke analize.
Abstract (english)
Kinetic analysis of isothermal thermal degradation of poly(ethylene oxide) of different molecular masses, using experimental data obtained by isothermal thermogravimetric analysis was performed. Using the integral “model-free” isoconversional method, it was found that for the broad area of conversion, the activation energy (E) does not depend on the conversion, which indicates a one-stage process. Kinetic model f( ), activation energy (E), and predexponential factor (A) are determined for each sample by applying a reduced time curve (RTP). The exact mathematical expressions of the kinetic model were obtained by comparison with the experimental data. Kinetic analysis was also carried out using the Netzch Thermokinetics program. The Thus obtained kinetic parameters E, A and f(α) are very well matched with the results already obtained by the model free isoconversional and RTP methods, which indicates the correctness of the kinetic analysis procedure.
