Polynitropolyphenylene is obtained from the reaction of a solution of
1,3-dichloro-2,4,6-trinitrobenzene in nitrobenzene at 150°–180 °C with
copper powder (Ullmann reaction).
The raw product obtained in this manner is first separated from copper
chloride and then cleaned in several stages from solvent residues and
low molecular weight elements. The resulting compound is a noncrystalline
explosive of extremely high thermal resistance. In the field
of W LOVA technology, it is used as an W Energetic Binder in high
ignition temperature propellants.
