Thermally induced reactions of solids: Isokinetic relationships of non-isothermal systems

Isothermal kinetics of (E)‐4‐(4‐metoxyphenyl)‐4‐oxo‐2‐butenoic acid release from a poly(acrylic acid‐co‐methacrylic acid) hydrogel

“…By comparing the values of E a, α and ln A α , one may conclude that the increase in ln A also coincided with the increase in E a , and this was the so‐called compensation effect 11. The existence of the compensation effect confirmed the previously exposed hypothesis about the complexity of the investigated process of MEPBA release from the PAA‐ co ‐MA hydrogel.…”

Application of the Weibull distribution function for modeling the kinetics of isothermal dehydration of equilibrium swollen poly (acrylic acid) hydrogel

“…The increase of lnA a is in a functional relationship with the increase of E a,a values (compensation effect [28][29][30]) and this relationship can be written in the following form:…”

A unified approach to kinetic processing of nonisothermal data

“…If uiso, estimated by the experimental value of Ti,, , is actually present [48,49] in the far IR-spectra, it is possible to specify a reaction group, the transformation of which is assumed to be the rate limiting step of the process. Successive substitution of values of lnA, and E, for reactions of one series into (12) and of b into (14) gives the Tiso value for a given conversion.…”
