Modeling solubility parameters and permeation data of organic solvents versus butyl gloves from four manufacturers

Abstract

AbstractA model based on the combination of Hansen solubility parameter theory and Flory‐Rehner polymer solution theory was used to determine the solubility parameters of butyl glove material provided by several different manufacturers using a nonlinear least‐square regression. To evaluate the validity of this model, weight gain data were collected for 26 solvents versus butyl gloves from four different vendors. Good correlation was found with R2 ranging from 0.858 to 0.961, which was attributed to extended weight gain testing and weight gain calculations based on glove sample weight after immersion and postdrying. Steady‐state permeation rates (molar steady‐state permeation rates), breakthrough times, and lag times for the butyl glove samples against solvents were determined and correlated to solvent‐polymer interactive term χϕp2. A high level of correlation was observed for all glove materials. Correlation was also made with permeation data collected from three of the four glove materials, and a high degree of correlation was found with R2 ranging from 0.8644 to 0.9369 for steady‐state permeation rates (molar steady‐state permeation rates), breakthrough times, and lag times. © 2008 Wiley Periodicals, Inc.
