The thermal decomposition and burning behaviour of acrylonitrile, containing nanoscopic sodium cloisite, and copolymerised with diethyl(acryloyloxy-1-ethyl) phosphonate (DEAEP), and 2-acrylamido-2-methylpropane sulphonic acid (AMPS) has been investigated. The presence of these copolymers which decompose to form nucleophiles improves the thermal stability and reduces the flammability. This occurs through the formation of a more stable char, containing more nitrogen, during the early stages of decomposition, which is less dependent on the presence of oxygen during its formation, and so continues to form when engulfed by a flame, in essentially anaerobic conditions.
