We have used the FT-IR/ATR technique to investigate TNT diffusion in acrylonitrile-butadiene rubber (NBR) at 93, 103, and 113 C. An analysis of the frequency and intensity of the NO2 symmetric and asymmetric stretch vibrations suggests that TNT diffused in NBR is in an isolated molecular state and/or cluster form. The diffusion process can be well-described by Fickian kinetics. The kinetic model fitting shows that the diffusion coefficient of TNT in NBR is on the order of 10-7cm2/s and the activation energy is in the range of 30-35 kJ/mol.
