Latest Patents
One of his latest patents is a process for the preparation of lightweight, planar molded articles. This invention focuses on creating articles with a thickness ranging from 0.1 to 40 mm and a density of 0.015 to 0.25 g/cm³. The process involves treating porous materials, such as open-celled or flexible polyurethane foams, with an effective amount of an aqueous dispersion or emulsion of organic compounds containing NCO groups. The isocyanate compound is allowed to cure, optionally while molding, at temperatures between 25°C and 180°C and at pressures from 1 to 50 bar. The resulting molded articles exhibit special mechanical properties, enhancing their utility in various applications.
Another significant patent involves polyisocyanurate/polyurethane elastomers based on crystallite suspensions. These suspensions contain 3 to 70 weight percent of a crystalline, ethylenically unsaturated polyester, which is prepared through condensation polymerization. The coherent phase consists of a polyhydroxyl compound with specific properties, suitable for preparing both non-cellular and cellular polyurethane or polyurethane group-containing polyisocyanurate foams.
