摘要： The invention relates to the use of polyethers containing urethane or urea groups as foam stabilizers, obtained by reacting at least one isocyanate with (a) at least one hydrophilic polyether which statistically carries at least one OH and/or NH2 and/or NH function and (b) at least one hydrophobic polyether which statistically carries at least one OH and/or NH2 and/or NH function and optionally (c) further compounds which carry at least one OH and/or NH2 and/or NH function and/or other isocyanate-reactive groups, such as carboxyl or epoxide functions, with the proviso that at least one isocyanate is ≧difunctional.
