摘要：

A dynamic absorption technique was employed to determine the solubility of benzene, hexane, and heptane in modified polyethylene films. Films were modified by solvent annealing, crosslinking, and combinations thereof. Solvent annealing was found to increase the solubility while crosslinking led to its diminution. The effect of combined treatment on the solubility was found to be dependent on the sequence of treatment, the swelling power of the conditioning agent, and the irradiation dose. A slight effect of the solvent‐diffusant pair was also observed. The solubility of the various vapors in crosslinked films was found to vary linearly with temperature. Solubility of some vapors in some of the conditioned films showed maxima with respect to temperature. The changes in solubility were explained in terms of the relative changes in the molecular volume of the diffusant and of the segmental mobility of the network chains with the various experimental conditions.
