Abstract
Process for the preparation of polyurethane foam materials, which are cold hardened, from polyethers having active hydrogen atoms, polyisocyanates, water, and/or other driving means, as well as eventually customary crosslinkers, characterized in that when In addition to the amine catalysts, customary in polyurethane chemistry, alkali metal salts of inorganic acid are introduced.
