The effect of temperature on both moisture sorption isotherms and the rate of sorption was adequately described by the Arrhenius law
so extrapolation of the experimental data to a slightly wider range of temperatures was considered a reasonable approach.
According to the Arrhenius law
this temperature rise induces in turn a decrease in viscosity (this effect increases with the initial viscosity) which has two main consequences.
The first relaxation process had similar behavior in nanocomposites as in the references, and the temperature dependence of the relaxation times obeyed the Arrhenius law
, also characteristic to [alpha]-relaxation processes.
The temperature dependence of the viscosity is supposed to follow an Arrhenius law
Phan-Thien/Tanner model and Arrhenius law
were used as a rheological model for the simulation.
This phenomenon is consistent with the Arrhenius Law
They are based on the isoconversional principle, which states that the reaction rate at constant extent of conversion is only a function of temperature through an Arrhenius law
The [gamma] mechanical relaxation has been observed at about -100[degrees]C at 1 Hz (8-11) This transition obeys an Arrhenius law
and the activation energy is about 50 kJ/mol (4, 9, 10).
The temperature dependence of viscosity was expressed by an Arrhenius law
as reported in the Appendix.
r], assuming the validity of the Arrhenius law
, showed only a moderate variation between samples designated 50K and 120K.
The frequency dependence of these relaxations was treated following the Arrhenius law
and Starkweather formalism.
11) of the acid and the ester amidation follow similar Arrhenius laws
