Abstract Details

2006, Doctor of Philosophy, University of Akron, Chemistry.
In this work, an improved nonlinear regression method based on the combination of the Hansen three-dimensional solubility parameter theory and the Flory-Rehner theory was successfully applied to estimating the three-dimensional solubility parameters of butyl glove materials. Excellent model fit was observed for all the butyl gloves from four different manufacturers. Unlike earlier work, only a single set of weighing factors were required, resulting in a more robust, convenient, and generally applicable model. Improved weight gain test was critical to the development of this model. The collected weight change data showed that it might take up to five weeks to reach equilibrium swelling for the butyl glove materials immersed in a series of organic solvents. Thus, extended immersion was necessary since equilibrium swelling was assumed in the theoretical context of this model. In addition, since the extraction of oligomers and additives from butyl glove materials was evidenced during weight change test, determining weight gain based on the post-drying glove sample weights should eliminate possible error source. Since this model is also related to the standard free energy changes of mixing for solvent/polymer systems, it has been demonstrated as a good predictor of the permeation properties of Viton® and Nitrile glove materials. In this work, the model was extended to butyl gloves from four different vendors. Attempts were made to collect permeation property data of the four butyl glove materials against a series of organic solvents, then correlate it using the described model. Excellent model fit was observed for all four individual butyl glove materials. With proper normalization approaches based on sample thickness, it was possible to use this model to correlate the combined permeation data from different butyl glove materials with different sample thicknesses. The results of this work further proved the effectiveness of this model in predicting the permeation performance of chemical protective clothing.
