摘要：
Polyurethane foams having a density of less than 200 g/l are prepared by reacting a) polyisocyanates with b) compounds having at least two hydrogen atoms reactive with isocyanate groups, the polyisocyanates a) being aromatic di- or polyisocyanates and the compounds b) having at least two hydrogen atoms reactive with isocyanate groups containing at least one acrylate polyol.
