Latest Patents

One of Harald Dauns' key patents is titled "Catalytic, solid state process for the preparation of linear polyamides." This patent describes a process for preparing linear polyamides by reacting the appropriate dicarboxylic acid and diamine in a liquid reaction medium. The process involves the addition of a catalytically effective phosphorus compound, followed by the removal of the reaction medium to yield a solid salt. The solid salt is then precondensed in the solid phase at a temperature ranging from 140°C to 5°C below its melting point. The condensation continues at a higher temperature until the desired degree of condensation is achieved. This innovative method has the potential to streamline polyamide production and improve material properties.
