dc.description.abstractThe thermal stabilities of metal polyacrylonitriles (MPAN) were studied by thermogravimetric analysis (TGA) between 25 and 550-degrees-C under nitrogen flowing at 10-degrees-C min-1. The metal contents of the polymers and their molecular weights are also reported. The kinetic data obtained by TGA showed that the thermostabilities of these polymers decrease in the order: Ge-PAN > Ga-PAN > Au-PAN > Sn-PAN > Bi-PAN > In-PAN > Pd-PAN > Sb-PAN. The experimental data suggest that the thermal stability of these polymers depends on the metal and the amount of metal incorporated. The reaction order for the one-step thermal decomposition of the polymers was found to be zero. The pre-exponential factor, the reaction order and the activation energies for the decomposition of the metal polyacrylonitriles were determined.
