Abstract  

Acrylonitrile-styrene /AN-St/ copolymers of different compositions were prepared, with and without ferric chloride by free radical polymerization. It was found using Mössbauer spectroscopy that reduction of Fe3+ to Fe2+ takes place during the polymerization. The addition of ferric chloride and the reduction of Fe3+ was found to influence the thermal stability of the copolymers.
