Title: The Innovations of Peter Loewrigkeit
Introduction
Peter Loewrigkeit is an accomplished inventor based in Wyckoff, NJ (US). He holds a total of six patents, showcasing his significant contributions to the field of polymer chemistry. His work primarily focuses on developing innovative polymer dispersions and processes that enhance the performance and stability of materials.
Latest Patents
Among his latest patents is the invention of an aqueous N-methylolhydrazide-containing polymer dispersion. This stable aqueous dispersion is effective for forming films that are resistant to both water and organic solvents. The polymer is a water-dispersible vinyl addition polymer that contains a sufficient proportion of pendant N-methylolhydrazide groups, allowing it to cure in situ on a substrate when applied and dried at ambient temperature. Additionally, the polymer includes pendant carboxylic salt groups that enhance its water-dispersibility or solubility.
Another notable patent is the stabilization of polyurethanes. This process provides water-based anionic polyurethanes with improved thermal oxidation color stability. The method involves using water-dispersed amine salts of anionic prepolymers, which are prepared from the reaction of polyhydroxy compounds and dihydroxy carboxylic acids with diisocyanates. When cured at temperatures exceeding 150 degrees Celsius, these products exhibit minimal discoloration and excellent mechanical properties.
