Decay of free induction in polyvinylchloride in the high elastic state

Abstract

An experimental study was made of the form of decay of free induction (ID) in PVC samples with different molecular weights in the high elastic state. It was found that the form of ID differs from the form predicted by a model of rotary Brownian motion with a single correlation time. For the theoretical description of the form of ID an attempt was made to use the existing theory, which assumes anisotropic motion of the polymer chain. © 1979.
