Title: The Innovation Journey of Hans-Dieter Mummenthey
Introduction
Hans-Dieter Mummenthey, a prominent inventor located in Wiesbaden, Germany, has made significant contributions to the field of polymer chemistry. With a total of three patents to his name, his work focuses on the development of advanced materials that have applications in various industrial sectors.
Latest Patents
Mummenthey's latest patents showcase his expertise in innovative chemical processes. One of his notable inventions is the "Process for the preparation of copolymers," which involves a multi-step reaction. This process begins with the reaction of an olefinically unsaturated dicarboxylic acid with a polyhydric alcohol to create a hemi-ester. This hemi-ester, rich in free hydroxyl groups, is then reacted with a monoepoxy compound to yield an olefinically unsaturated diester that is copolymerized with unsaturated monomers lacking free carboxyl groups. The resulting product can be isolated or hardened with a hardening agent, leading to valuable coating and adhesive compositions.
Another significant patent by Mummenthey is related to "Low-viscosity air-drying alkyd resins." This invention describes an air-drying alkyd resin composed of a dicarboxylic acid, a non-drying monocarboxylic acid, and a drying fatty acid, among other components. The resin undergoes modifications through a reaction with a monofunctional oxirane compound, ensuring it remains lightweight and efficient with a viscosity not exceeding 450 mPa.s and an acid number below 15. This resin has vast potential for use in various coated articles and industrial applications.
