Title: Gerhard Trummelmeyer: Innovator in Polymer Chemistry
Introduction
Gerhard Trummelmeyer is a notable inventor based in Leichlingen, Germany. He has made significant contributions to the field of polymer chemistry, particularly in the development of polyester polyols and their applications. With a total of 2 patents, Trummelmeyer has established himself as a key figure in his industry.
Latest Patents
Trummelmeyer’s latest patents include innovative formulations that enhance the performance of polymer systems. One of his patents focuses on polyester polyols that serve as anchoring agents for polymer systems. These new polyester polyols possess an acid value below 10, a hydroxyl value ranging from 50 to 200, and a hydroxyl functionality above 2. They are characterized by a number average molecular weight of 800 to 5,000 and are liquid at 23°C or homogeneously soluble in di-2-ethylhexyl phthalate at a concentration of at least 70% by weight. The viscosity of the 70% solution is between 1 to 35 Pa.s, making them effective as anchoring agents and polymeric plasticizers.
Another significant patent involves the use of liquid, cold-hardening polyurethane-urea-forming components. This invention relates to special combinations of starting components that are suitable for corrosion-inhibiting wear prevention through casting, centrifugal casting, or spraying. The components are liquid, low viscosity mixtures of polymer-containing or polyadduct-containing polypropylene oxide polyols and/or ethylene oxide-containing polypropylene oxide polyols. These are reacted at room temperature with liquid polyisocyanates based on diphenyl methane diisocyanate or their NCO-prepolymers with polyether polyols.
