He was based in Munich, Germany, and is remembered for his innovative approach to the preparation of polycondensates. His work has been influential in various industrial applications.

Latest Patents

Janssen held a patent for the "Preparation of polycondensate by one-step melt condensation in a vacuum." This patent describes an improvement in the method of preparing a linear polycondensate of high molecular weight. The process involves forming a precondensate that is subjected to a one-step melt condensation in a vacuum while removing cleavage products. The method emphasizes the use of a molten precondensate with an average condensation degree of at least 3, which is continuously introduced into the melt condensation zone. The reaction mass is stirred to achieve a specific melt viscosity, allowing for the continuous withdrawal of molten polycondensate.
