Abstract
A method for the preparation of highly elastic foams of reduced compression hardness and having urethane groups is disclosed, in which the reaction of the polyurethane-forming materials is carried in the presence of 0.01 to 5% by weight, based on the polyol, of a compound, which has at least one polyoxyalkylene group and at least one anionic group in the molecule. The use of fluorocarbons to decrease the compression hardness can reduced appreciably by the use of this compound.
