Abstract

Procedure for preparing polyfuran foams by polymerization, alternatively copolymerization of furfuryl alcohol, if desired in combination with prepolymers, alternatively precopolymers of furfuryl alcohol, in the presence of a strong acid, being in a liquid condition, characterized by using a starting material, in which at least 50% of the hydroxyl groups, present in the furfuryl alcohol prepolymer mixture, come from the free furfuryl alcohol, while the reaction is carried out in the presence of an acidic compound or a mixture of acidic compounds, having a value pKa in water 1 to 4, if desired evenly distributed in mono or polyols, including polyether polyols, which do not polymerize in the presence of the used acidic compound, alternatively an acidic compound or a mixture of acidic compounds having a pKa value in water of less of 1, evenly distributed in said mono- or polyols.
