Kinetics of nitroglycerine migration through unsaturated non‐halo and halo polyesters

The diffusion coefficients (D) of nitroglycerine (NG) migration through cured non‐halo and halo polyesters have been calculated with the help of M∞ determined experimentally and Fick's Law. The calculated NG migrations at different time intervals compare very closely with the corresponding NG migrations determined experimentally. The concentration profiles at various locations in thin sheets of non‐halo and halo polyesters have also been calculated.
