Unsteady‐state conjugate sorption curves for carbon tetrachloride in low‐density polyethylene (LDPE) pellets at temperatures between 40 and 70°C suggested there was a maximum in the diffusivity‐concentration relationship at high values of concentration. The sorption curve at 70°C also displayed features characteristic of pseudofickian behavior, which was attributed to clustering of the penetrant at the high vapor acitivity corresponding to this temperature.
