A study of the effects of storage at 65.5 and 80 C on the stabilizer content and viscosity of ARP propellant was made. The viscosity results were erratic but, like the stabilizer results, were found to show a definite deterioration trend. Least square analyses of both the viscosity and stabilizer data led to the derivation of simple, linear equations relating these properties with time at either of the temperatures studied. The relationship was extended to any temperature, by application of the Arrhenius equation, so that it is now possible to predict the viscosity or stabilizer content of this type of propellant any desired time at any given storage temperature. The need is shown for obtaining more information concerning the validity of the predictions as well as relating these laboratory tests with storage safety and functioning.
