Theoretical Analysis of Relaxation Processes in Acrylate Latex Polymers

Dissipative processes in highly elastic latex polymers have been analyzed based on a theoretical calculation of the relaxation microheterogeneity of polymer structures. The microheterogeneity is evaluated graphically from the dependence of the dissipation intensity ratio λ/λ max on the temperature r...

Description
Summary:Dissipative processes in highly elastic latex polymers have been analyzed based on a theoretical calculation of the relaxation microheterogeneity of polymer structures. The microheterogeneity is evaluated graphically from the dependence of the dissipation intensity ratio λ/λ max on the temperature ratio ( Т – Т max )/ Т max . The α-relaxation intensity is determined using the internal friction spectrum recorded by dynamic relaxation spectroscopy.
