Abstract
A novel polyimides of polystyrene with high thermal stability were prepared by the reaction of aminated polystyrene with Benzophenone tetracarboxylic dianhydride. The aminated polystyrene were prepared from the nitration of polystyrene followed by chemical reduction of its nitro groups. Infrared (FT-IR) spectra and thermogravimetric analysis (TGA) were used to characterize polymers . The prepared polymer exhibit good thermal and thermooxidative stability at polymer decomposition temperature greater than 550°C in air atmosphere . Another attractive feature is their high char yields 75% at 650°C in air atmosphere.
