Abstract : Polymeric binders for plastic bonded explosives. The binders are prepared from polyfunctional orthonitrophenols and polyisocyanates. The binders will reversibly dissociate when subjected to temperatures the range of from 100 to 150 C. Essentially, this invention comprises preparing a polymeric binder for a plastic bonded explosive (hereinafter sometimes referred to as a PBX) that will dissociate into the monomers from which it was made or to liquid oligomers if it is heated to a temperature in the range of from about 100 to 150C. The reversibly dissociable polymeric binders are prepared by mixing certain hereinafter specified polyfunctional ortho-nitrophenols with certain hereinafter specified polyisocyanates, adding a catalyst that promotes the formation of a polyurethane and allowing a polyurethane to form.
