The physical characteristics of synthesized polysilylether (PSE) polymers used as high solids loading binders for an energetic material are described, and related methods. These physical characteristics ranged from fluid-liquids to oily-liquids, to pastes, to viscous goos, too taffy-like materials, and too thermoplastic solids. For the most part, thermal decomposition temperatures were high, while glass transition temperatures were low, indicating a good operating range for most of the PSE polymers. Two PSE polymers characterized as thermoplastic solids had ideal softening and melting temperatures for use in filament generation and extrusion of high solids loading binders.
