Latest Patents
Yukichi Tanaka holds 1 patent related to the preparation of polyoxyalkylene polyols and polymer polyols. His patent describes a method where propylene oxide is added to an active hydrogen compound in the presence of an alkali metal hydroxide catalyst. This process occurs at a reaction temperature ranging from 60 to 98 degrees Celsius and at a pressure of less than or equal to 4 kg/cm². The resulting polyoxyalkylene polyol has a hydroxyl value of 10 to 35 mg KOH/g, a monool content of less than or equal to 15 mol %, and a Head-to-Tail bond selectivity of greater than or equal to 96 percent. The polymer polyol is created by polymerizing an ethylenically unsaturated monomer in the polyoxyalkylene polyol. This innovation leads to the production of flexible polyurethane foams that exhibit improved properties such as hardness and impact resiliency.
