By World War II, perchlorates were used mostly for solid rocket motors, which account for most of the emerging perchlorate problem in this country. Besides rocket fuel, perchlorates are used in 3-inch and 4.2-inch mortar shell illumination rounds, perimeter illumination booby traps, artillery simulators used in training, signal flares, smoke pots, artillery tracers, and railway torpedoes. 

Urethane polymers are important in many fields other than home improvement and, in some of these cases, the ability to easily estimate the degree of cure can be very important. For example, in the manufacture of certain types of fuel for use in rockets, solid propellant is mixed with a urethane binder and very slowly cured in small batches. It is important for reasons of both safety and performance that the correct degree of curing is achieved. To illustrate the application of fiber optic mid-IR spectroscopy to this problem, a simulated rocket fuel mixture was obtained from an industrial partner. The material comprised a simulated propellant mixed with an uncured urethane precursor curing of this particular mixture is typically carried out batchwise at a temperature of 50°C over a period of several days. The use of a direct, in-situ probe capable of giving a clear indication of the state of cure of each batch would be of great utility. 

Suspension I was prepared to simulate a solid rocket fuel and contained 76,5 percent by volume of solids in a hydroxyl terminated polybutadiene (HTPB) matrix in which di-octyl-adipate, EX)A, was used as an antioxidant. The matrix was a Newtonian fluid with a shear...
