Abstract

A diisocyanate crosslinking agent having a minimum chain length of methylene groups from 25 to 45 which has a coiling-uncoiling ability in a cured solid propellant composition (under stress and relaxing of stress) as a result of the chain length and configuration imparts superior structural strength to the solid propellant composition. A preferred species is 1,37-heptatriacontane diisocyanate, OCN-(CH2)37-NCO, which is employed as an effective crosslinking agent in hydroxyl-terminated polybutadiene propellants.
