Abstract
A catalytic system for use in the formation of polyurethane propellants in which compounds of the type Fe (AA).sub.2 X, where AA is the acetylacetonate radical and X is an acid radical. These compounds have been found to be valuable catalysts for promoting the alcohol-isocyanate reaction at room temperature.
