Polysulfides inert binder

Figure 4.5 shows the chemical processes and molecular structures of typical inert binders used in composite propellants and plastic-bonded explosives.Ph Polysulfides are characterized by sulfur atoms in their structures and produce H2O molecules during the polymerization process. These H2O molecules should be re-... 

There are a number of inert binders such as polyester, epoxy, polysulfide, polyurethane which have been reported as binders for composite propellants and plastic bonded explosives (PBXs). At present, hydroxy-terminated polybutadiene (HTPB) is regarded as the state-of-the-art workhorse binder for such applications. However, the recent trend is to use energetic binders such as poly [3,3-bis(azidomethyl oxetane)] [poly(BAMO)], poly (3-azidomethyl-3-methyl oxetane) [poly(AMMO)], PNP, GAP diol and triol, nitrated HTPB(NHTPB), poly(NiMMO), poly(GlyN) and nitrated cyclodextrin polymers poly(CDN) for PBXs and composite propellants in order to get better performance. 

In the earhest and also the simplest configuration [4], the positive electrode includes sohd sulfur and carbon black (or other inert material with high electronic conductivity), the negative electrode is lithium metal, and the electrolyte contains lithium salt dissolved in organic solvents. Suitable binders are used to maintain the integrity of the electrode stracture [4, 23]. The observed poor discharge efficiency is attributed to the formation of soluble polysulfides, which diHiise between cathode...
