Abstract of the Disclosure: A process for the manu- facture of a resilient foam based on a melamine- formaldehyde condensate, wherein an aqueous or alcoholic solution or dispersion containing a melamine-formaldehyde precondensate, an emulsifier, a blowing agent and a hardener is foamed by ultra-high-frequency irradiation and the foam is hardened by crosslinking the preconden- sate. The foam may be employed for heat and sound insulation, and as a packaging material.
