| Abstract: | Differential sorption data of benzene and n-hexane vapors in polyethylene have been obtained over wider ranges of temperatures and activities than available before. The data are used to develop a better model or help in the choice of the appropriate theory and modeling assumption from the available ones. Whereas the swelling of the walled-in amorphous region, with some modifications, provides the best correlation for the solubilities, in contrast, the integrated giant crosslink model shows remarkable agreement with the experimental values of diffusivities. |
