An approach to high‐density, high‐modulus binders for explosives is to blend low‐density, high‐modulus polymers with high‐density, low‐modulus polymers. Improved properties, which these pairs theoretically should have, are discussed. Two attempts to achieve miscibility between a high‐density fluoropolymer (Kel‐F 800) and high‐modulus thermoplastics (Lucite 130 and Phenoxy PKHJ) were unsuccessful. These blends are immiscible and their physical properties are additive or only slightly enhanced. Anelastic properties of the blends indicate phase separation by the presence of two glass transitions, one associated with each phase.
