Molecular Relaxations in Substituted Polystyrenes,nces of intermolecular origin (1,2). Perhaps the only exceptions to this rule are the cyclohexyl group chair- chair transition (3) and some low temperature methyl group rotations (4). In a previous study (5) of polystyrene systems, evidence was found to suggest that phenyl group rotation could only

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. These results are in fair accord with acous

Greater detail may be obtained by comparing measured values of dipole moment with those calculated by means of the rotational isomeric state model (2) (RISM), providing there is adequate knowledge of the statistical weights and geometric parameters

Sogenannte Involutionspsychosens approximated by a linear mechanical model consisting of a chain of torsional springs, dashpots, and beads bearing dipoles. The equations of rotational motion can be solved analytically for this model. We derive an expression for the correlation length, a measure of the extent to which rotational m

The time dependent behavior of molecular configurations is developed from rates for passing over internal rotational energy barriers. Configurational perturbations caused by electric
