Thiokol Minuteman First Stage propellant used acrylic acid to produce the HB polymer used as the binder. The original supplier of acrylic acid stopped production and Thiokol then obtained acrylic acid produced by the Taft, Louisiana Plant of Union Carbide Co. To assure that this new source of supply was a satisfactory replacement, Thiokol ran qualification testing on the new material See TWR-4716, May 1972 - ADB-894 033L. and found it satisfactory. In the Thiokol program two motors were cast in 1971 and propellant from the mixes were cast into cartons for a ten year test program. This propellant was then transferred to this laboratory and testing on a yearly basis was started in 1975. Due to insufficient propellant, the full ten year program was not possible. Testing was completed after nine years and this is the final report. From an analysis of the data the propellants physical properties are satisfactory and the stability, with respect to age, is satisfactory.
