    摘要: This invention relates to novel furan polyols, which are characterized in that they are the product of reaction of a strain selected from the group or consisting of a polyalcohol, a monoamine or polyamine, said polyalcohol or said amine possibly containing a furan cycle and mixtures thereof with a chain extension agent constituted by an organic epoxide, with the proviso that this organic epoxide is a furannic oxiran when this polyalcohol does not contain a furan cycle with the exclusion of 2,5(bis-hydroxy)furan as sole strain, when the chain extension agent does not contain any furan cycle. These furan polyols are used for the preparation of polyurethane foams having improved properties.
