“…is is the first observation in polymers. Additionally, because the EPDM contains the flexibly attached dipolar side groups (methyl group [-CH 3 ]), the value of Δε of the β-relaxation was smaller than that of α-relaxation at low temperature [47,48]. e activation energies for β and MWS dielectric relaxation phenomena were also determined by the Arrhenius temperature dependence of equation ( 3).…”

The dielectric permittivity of synthetic rubber polymers, nitrile butadiene rubber (NBR) and ethylene propylene diene monomer (EPDM), with both frequency and temperature variations, was thoroughly investigated by dielectric relaxation spectroscopy (DRS). The spectrum versus frequency of DRS was analyzed with the semiempirical Havriliak–Negami formula and conductivity contribution by employing the newly developed “dispersion analyzer” analysis program. The main dielectric relaxations called the α- and β-processes, associated with the cooperative motion of chains in polymers, were discovered in the low-temperature region. In the high-temperature region, we found Maxwell–Wagner–Sillars (MWS) relaxation associated with polymer interfacing and normal-mode (α’) relaxation responsible for end-to-end dipole vector motion. The activation energies of schematic molecular chains responsible for the relaxation processes were obtained with the information about its motional mode. The glass transition temperature and dipole moment for the side group were also determined and compared with those from previous studies. In the EPDM specimen, the peaks of α- and β-relaxation merged at high temperature and were separated with decreasing temperature. The first observations of both merging and splitting were consistent with the results on the temperature dependency of the relaxation strength. Both contour mapping and three-dimensional plots for the two rubbers provide visual information for the distribution and mapping of relaxation.

De l’hyperinflation au « miracle monétaire » : l’expérience hongroise de 1945-1946

Entre août 1945 et juillet 1946, la Hongrie a connu la pire crise inflationniste jamais recensée. Aux derniers moments de cet épisode, les prix augmentèrent de 150 000 % par jour. Cette séquence a donné lieu à de nombreuses analyses, que ce soit au moment de l’envolée des prix avec les articles de Kaldor et Nogaro, ou par la suite avec les travaux de Cagan ou de Sargent et Wallace. Cependant, l’approche monétariste échoua à fournir une explication satisfaisante de ce cas, que ce soit dans la modélisation des comportements pendant la flambée des prix, ou dans l’explication de la sortie de crise. Nous revenons sur cet épisode pour insister en premier lieu sur la politique très particulière d’indexation de la monnaie qui a instauré un régime bimonétaire ; dans un second temps, on s’attache à la stratégie de stabilisation et à ses effets distributifs. Finalement, la prise en compte de ces éléments permet d’élucider la virulence de la crise hongroise. Classification JEL : B22, E31, E42, N14.
