摘要：

The kinetic equations of polyurethane foam weight loss have been determined and the influence of the atmosphere; using nitrogen and air, has been analyzed. The results of the kinetic constants obtained from isothermal and dynamic experiments have been related. A comparison between the kinetic constant values corresponding to nitrogen and air atmospheres has also been performed. The significance of using the values of solid weight that can be lost at a given temperature is analyzed.
