Title: The Innovations of Teruhiko Ohara
Introduction
Teruhiko Ohara, an esteemed inventor based in Tokyo, Japan, is credited with six patents that showcase his significant contributions to the field of polymer chemistry. His work focuses on innovative methods and materials, particularly in the production of polycarbonate diols and environmentally friendly polyurethanes.
Latest Patents
Among Teruhiko Ohara's most recent innovations are his patents for a "Polycarbonate diol and producing method thereof" and "polyurethane and active energy ray-curable polymer composition both formed using same." These patents describe a novel polycarbonate diol that serves as a crucial raw material for crafting high-performance polycarbonate diol-based polyurethanes, characterized by exceptional hardness, abrasion resistance, and hydrophilicity. The resulting polyurethane finds diverse applications in paints, coatings, synthetic leathers, and high-function elastomers. Additionally, the polycarbonate diol can be utilized in creating a radiation-curable polymer composition that offers superior contamination resistance and significant hardness. The production process involves a reaction between two specific diols and diester carbonate, facilitated by a transesterification catalyst containing metals from Groups 1 or 2 of the periodic table, in very low concentrations (100 weight ppm or less).
Another innovative patent addresses the "biomass-resource-derived polyurethane, method for producing same, and biomass-resource-derived polyester polyol." This invention outlines a method for synthesizing a biomass-resource-derived polyurethane by reacting a dicarboxylic acid with an aliphatic diol to create a polyester polyol, followed by its reaction with a polyisocyanate compound. The dicarboxylic acid utilized contains biomass-derived components, which contributes to environmental sustainability in polymer production.
