Selection of a Relaxation Function to Describe the Dissipative α-Relaxation Process in Latex Polymers

Discrete relaxation times D (τ) in latex polymers are calculated using the phenomenological model of a standard linear body and continuous relaxation time spectra H (τ) involving the Kohlrausch function in the temperature range from –150 to +250°C. The higher relaxation inhomogeneity of the modified...

Description
Summary:Discrete relaxation times D (τ) in latex polymers are calculated using the phenomenological model of a standard linear body and continuous relaxation time spectra H (τ) involving the Kohlrausch function in the temperature range from –150 to +250°C. The higher relaxation inhomogeneity of the modified polymers confirms the previously obtained experimental data on its estimates across the width of the continuous spectrum of relaxation times with the involvement of dependence λ/λ max = f {( Т – Т max )/ Т max }.
