Abstract

The curves describing the relaxation behavior of poly (4-(acryloxy) phenyl)(4-chlorophenyl) methanone at several frequencies present in the dielectric loss-temperature plane ap relaxation centered at-76" C at 10 Hz, whose activation energy shows a slight tendency to increase as the temperature goes up. The relaxation spectra exhibit an ostensible glass- rubber relaxation or a process centered at 106" C at 10 Hz, in which free charge ...
