Dielectric Dispersion in Dilute Solutions of Several Para-Substituted Polystyrenes,from about -10°C to +30°C. For polymers of 4-fluorostyrene and 4-chlorostyrene, as well as for a styrene/ 4-vinylpyridine 2/1 copolymer, the frequency of maximum dielectric loss at 300°K is about 30 to 40 MHz and the activation energy is about 5 kcal/mole.
