Abstract
The kinetics of the hydrogen getter 1,4-bis(phenylethynyl)benzene (DEB) ble nded with carbon-supported Pd (DEB-Pd/C) dispersed uniformly in silicone [D EB-Pd/C-poly(dimethyl siloxane)] were studied with a thermogravimetric meth od as a function of the hydrogen pressure and temperature. A diffusion-cont rolled reaction model was developed to explain the experimental results. Th e diffusion coefficient, solubility coefficient, and permeability of hydrog en through silicone rubber were determined. (C) 2001 John Wiley & Sons, Inc .*
