The dielectric relaxation spectra of poly(2-ethoxyethyl methacrylate) in the frequency domain exhibits above Tg and at high frequencies a well-developed secondary  relaxation. This process is followed in decreasing ...
[EN] The temperature dependence of both the permeability and diffusion coefficients of carbon dioxide, oxygen and nitrogen in annealed LLDPE films are studied. It is found that the values of the permeability coefficient ...

[EN] The effect of annealing on the permeation of oxygen, nitrogen, and carbon dioxide through
coextruded linear low-density polyethylene (LLDPE) films is studied. The results indicate that the
permeability coefficient P ...

The effect of combined electromechanic force fields in nematic side chain liquid crystal elastomers will be analyzed. A biaxially stretched plate in the x- and y-directions under an electric field applied in the perpendicular ...
[EN] The relaxation behaviour of coextruded linear low-density polyethylene (LLDPE) films, prepared from copolymers of ethylene-1-octene, is reported. The spectra, expressed in terms of loss tan delta, present a gamma ...
