A process for producing a nanoporous amino resin foams, comprising the steps of a) providing an aqueous micellar emulsion template, comprising a block copolymers based on ethylene oxide and propylene oxide, b) by adding an organic micelle expander, c)combining the expanded micelle from step b) with an amino resin, d) adding an curing catalyst, e) optionally adding an organosilane and/or an organoamine, f) optionally adding polyvinylformamide, g) curing the amino resin above 50°C to obtain a gel, h) optionally replacing water and micelle emulsion template by a solvent with a boiling point at atmospheric pressure below 100°C, and i)drying the gel at ambient temperature and atmospheric pressure. |
