摘要：

The swelling of SBR by an aromatic oil has been experimentally studied at temperatures ranging from ambient to 200 degree C with thermally stable networks. A model based on Fick's law was developed, and the change of geometry of the elastomer sample was taken into account. The proposed approach is global or macroscopic, and a constant diffusion coefficient has been defined. The diffusion number, N//D, defined by two characteristics of a solvent-polymer system, t//f the swelling time and t//D, the diffusion time, represents an important result for engineering applications; it allows prediction of the behavior of amorphous elastomers in contact with a diffusing organic liquid.
