- Abstract
The article presents a study of the diffusion attenuation nuclear magnetic resonance (NMR) spin echo of elastic polymers. The study suggested a common theoretical method to calculation of the diffusion attenuation signals of each spin echo and a standard for magnetic field gradient pulse arrangement. It reported data on stochastic processes in polymers with varying topology and molecular mobility. It was shown that self-diffusion coefficient (D) is the mean chain length's logarithmic function.
