PURPOSE:To obtain the titled composition capable of increasing the volume of emitted gas in thermal decomposition with a small amount of the unreacted residual nitrite in foams, by wetting an azodicarbonamide with an aqueous solution of a nitride, drying and pulverizing the resultant azodicarbonamide. CONSTITUTION:A composition obtained by wetting an azodicarbonamide with an aqueous solution of a nitride, preferably sodium nitrite or potassium nitrite, drying and pulverizing the resultant azodiacarbonamide. The amount of the nitrite used is preferably 5-50pts.wt. based on 100pts.wt. azodicarbonamide in a dry state.
