Title: The Innovative Contributions of Steffen Kühling
Introduction
Steffen Kühling, an accomplished inventor based in Meerbusch, Germany, is known for his significant contributions to the field of polycarbonate production. With an impressive portfolio of 17 patents, his work has influenced various applications in materials science and manufacturing.
Latest Patents
One of Kühling's latest patents is centered around a method of producing polycarbonates. This innovative process involves the phase boundary method, where at least one dihydroxydiarylalkane in the form of alkali metal salts is reacted with phosgene. Conducted in a heterogeneous phase, the reaction takes place in the presence of sodium hydroxide solution and an organic solvent. Notably, the process minimizes the content of metals such as iron, chromium, nickel, zinc, calcium, magnesium, and aluminum. After separation of the organic solvent, the resulting polycarbonate can be worked up, yielding a substance that is particularly advantageous for creating transparent shaped articles. Additionally, Kühling has developed polycarbonate substrates characterized by a low concentration of defects, making them suitable for molded items with minimal cloudiness.
