Title: Innovations of Wilhelm Oppermann
Introduction
Wilhelm Oppermann is a notable inventor based in Herrenberg, Germany. He has made significant contributions to the field of polyurethane elastomers, holding two patents that showcase his innovative approach to material science. His work has implications in various industries, particularly in textiles and manufacturing.
Latest Patents
Oppermann's latest patents include a method for producing polyurethane elastomer fibers and the fibers produced according to this method. The invention concerns a polyurethane elastomer containing structural units of type (a), where the group —O—R—O— is a macrodiol group with a molecular weight of approximately 500 to 10,000. The variable R represents a bivalent aliphatic, cycloaliphatic, and/or aliphatic-cycloaliphatic group, while X is a short-chain olefinically unsaturated group. Y can be either NH or O, with n being an integer from 1 to 10 and m being an integer of at least 4. The invention also details a method of preparing this polyurethane elastomer, which can be melt-spun to form fibers or melt-extruded to create foils. The fibers or foils can be exposed to energy-rich radiation, leading to crosslinking of the polyurethane. The resulting fibers exhibit superior textile-mechanical properties, including good tensile strength, elongation at tear, residual elongation, and heat distortion temperature.
