Abstract

See full text

A process for manufacturing a solid thermoset foam includes the following successive stages: (a) providing an expandable and thermosetting composition including a first reactant chosen from reducing sugars and a second reactant chosen from primary amines, primary amine acid addition salts, secondary amines, secondary amine acid addition salts, and ammonium salts of formula Rn−(NH4+)n where n is an integer at least equal to 1 and Rn− represents the residue of an organic or inorganic acid; (b) introducing the expandable and thermosetting composition into a mold or applying the expandable composition to a support so as to form a film having a thickness at least equal to 1 mm; and (c) heating the expandable and thermosetting composition to a temperature at least equal to 140° C. to react the first reactant with the second reactant and to form, by polymerization and chemical foaming, a block of solid thermoset foam.
