This report describes development work on an improved pyrotechnic binder system. A liquid polymer system of low viscosity was desired to allow pour cast production of flare and marker compositions. High percentage composition of oxygen in the binder polymer was sought to minimize degradation of flare performance. Laboratory scale syntheses of several saturated hydroxyl-terminated liquid prepolymers and two cure reactions are described. A limited demonstration of pour castability of an illumination pyrotechnic composition was achieved with one liquid prepolymer cured as a polyurethane.
