Abstract:

Influence of the presence of plasticizer on the transport properties for the polychloroprene 1,4-dioxane Neoprene1,4-dioxane system has been investigated. The sorption rate curves for the extracted and the unextracted as received Neoprene demonstrated some characteristic, of Fickian behavior. The sorption isotherms obtained from the weight uptake did not coincide for repeated runs of the extracted sample they were below the isotherm of the unextracted sample. However, both types of samples extracted and unextracted Neoprene showed diffusion coefficients that increase with concentration. The difference between the diffusion coefficients for the extracted and unextracted Neoprene was not significant the extraction primarily affected the solubility.
