Abstract

The pulsed field gradient spin echo method was used to measure the diffusion of ten paraffin hydrocarbons in several uncrosslinked rubbers at 51Β°C. We obtain various free volume parameters from the concentration dependences, establish the approximate proportionality of the translational friction coefficient to paraffin molecular weight, and confirm the equal intrinsic efficiency of the diffusion mechanism of decane and hexadecane in rubbers.

Over the past decade several pulsed field gradient stimulated-echo methods have been presented for diffusion measurements in heterogeneous media. These methods have reduced or eliminated the coupling between the applied magnetic field gradient and a constant internal magnetic field gradient caused b

We describe a new and powerful computer program called TRIPLE\_GRADIENT which calculates optimized pulsed field gradient sequences for specific coherence pathway selection or rejection. Sequences can be computed for gradient coils acting along one, two, or three perpendicular axes. The program is ba
