Modeling and rheology of HTPB based composite solid propellants
Polymer Composites, 1998 AbstractThe propellant with the minimum viscosity required for a defect‐free casting can be obtained by proper selection of the size and fractions of solid components leading to maximum packing density. Furnas' model was used to predict the particulate composition for the maximum packing density.

Purification and Properties of Polyvinyl Nitrate and Its Compatibility With Solid Oxidizers
Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Polyvinyl nitrate (PVN) is a nitrate‐ester energetic binder that can be produced directly from polyvinyl alcohol—a cheap commodity feedstock—thereby offering potential cost and supply‐chain advantages over binders based on nitrocellulose and other specialty polymers.
