摘要
The pulsed‐gradient NMR method of Stejskal and Tanner was used to measure the diffusion of oil in synthetic cis‐polyisoprene. The diffusion encounters no barriers with spacings at least up to several μm and generally displays free‐volume behavior, obeying the WLF temperature dependence between −10°C and +130°C, and the Fujita‐Doolittle concentration dependence between 10 and 90 vol‐% oil.
