Abstract

The permeation rates of alkanes, alcohols, and aromatic hydrocarbons through untreated, fluorinated, and sulfonated high-density polyethylene (HDPE) were measured at a variety of temperatures and solvent compositions. The results were then analyzed to separate the individual contributions that solubility and diffusion make to the overall permeation rate. These results are discussed in terms of the chemical characteristics of the permeating constituents, and the barrier treatments on the HDPE surface.
