Determination of mechanical parameters related to the kinetics of swelling in an electrically activ thermally crosslinked polyacrylic acid (20% by weight) and polyvinylalcohol (80% by weight) (PAA-PVA) gel..Either thin films on spherical samples have been used in the experiments. The characteristic time of swelling in the case of a thin film has been found to be proportional to the square of a li

Dielectric and thermal relaxations in amorphous and semicrystalline poly(ethylene terephthalate), of the amorphous layer between neighboring lamellae. The fluctuation model proposed by Donth was used to estimate the size (1–3 nm) of the cooperative, rearranging regions connected with the glass transition in these samples. There occurs a hindrance of the cooperative motions due to the crystallin

Dielectric relaxation processes in poly (epoxypropylcarbazole) layers,f complex dielectric constants were measured in the frequency range from 10 to 10. Hz at temperatures 273 to 420 K. The experimental results lead to the conclusion that near .. the observed relaxations are essentially associated with the cooperative nature of the carbazole units motions without the
