Polynitropolyphenylene, a high‐temperature resistant, Non‐crystalline explosive

Upon looking for energetic, heat‐resistant nitropolymers we selected aromatic compounds containing nitro groups, the synthesis of which is based on the Ullmann reaction. Using dichlorotrinitrobenzene as the basic substance, we prepared polynitropolyphenylene in nitrobenzene by co‐using copper powder. These consist of nitrated benzene chains of different lengths. Depending on production and processing, polymers with a variety of characteristics are prepared. Their characteristics are described herein. They are distinguished by thermal stability, low crystallization and energetic behaviour. Combined with inert binding agents and perhaps softeners, they may be used as high‐temperature resistant explosive binding agents.
