Latest Patents
Hartmann holds a patent for a method of producing a polyamide molding compound. This method involves several key steps, including the addition and dissolving of m-xylylene diamine and dicarboxylic acids, such as adipic acid and aromatic dicarboxylic acids, in a dissolving chamber. The process is characterized by a polycondensation performed at a pressure of no more than 10 bar and a temperature range of 255°C to 270°C. The unique aspect of her method is the reduction of pressure to atmospheric conditions immediately after reaching the maximum temperature, while maintaining the temperature for continued polycondensation. Additionally, the granulate produced undergoes underwater crystallization before drying. Hartmann's innovative approach is encapsulated in her 1 patent.
