摘要：

The thermal stability of metal polystyrene was determined by thermogravimetric analyses (TGA) from 25 to 250-degrees-C under nitrogen flow. The kinetic data obtained by TGA show that the thermostability of these polymers decreases in the following order: Pd-PS > Au-PS > Bi-PS > Cu-PS > In-PS > Ga-PS > Sb-PS > Ge-PS. The data might indicate that the thermal stability of these polymers is related to the metal attached to the polymer chain. The energies of activation of the metal polystyrenes were determined. The order of reaction for the thermal decomposition of these metal polymers was zero. The pre-exponential factor and decomposition temperatures were determined.
