Abstract

The invention relates to a composite material, comprising at least one superabsorbent polymer and at least one elastic aminoplastic foam as a supporting material, to hygienic products, sealing materials, insulating substances, drying agents, water accumulators, packagings and artificial plant substrates, containing a composite material, and to a method for the production of a composite material that contains at least one elastic aminoplastic foam as a supporting material and at least one superabsorbent polymer, said method comprising the steps: A) providing an aqueous solution or dispersion that contains precursor compounds of the at least one elastic aminoplastic foam and optionally other additives; B) adding at least one superabsorbent polymer to the aqueous solution or dispersion of step A); and C) polymerizing the precursor compounds of the at least one elastic aminoplastic foam in the aqueous solution or dispersion of step B), in order to obtain the composite material by heating.
