    摘要： The present invention relates to a method for producing flexible polyurethane foams, wherein a polyol component which comprises polyricinoleic acid esters is used as starting substance. The flexible polyurethane foams according to the invention have a bulk density according to DIN EN ISO 3386-1-98 in the range of ≧10 kg/m3 to ≦150 kg/m3, preferably ≧20 kg/m3 to ≦70 kg/m3, and in general their compressive strength according to DIN EN ISO 3386-1-98 is in the range of ≧0.5 kPa to ≦20 kPa (at 40% deformation and 4th cycle). The polyricinoleic acid esters are obtainable by the reaction of ricinoleic acid with an alcohol component which comprises mono- and/or polyhydric alcohols with a molecular mass of ≧32 g/mol to ≦400 g/mol, the reaction being carried out at least in part in the presence of a catalyst.
