Latest Patents

Jong Yeol Choi holds a patent titled "Method for preparing polymer polyol stabilizer using maleic anhydride, and polymer polyol stabilizer prepared thereby." This patent discloses a novel stabilizer for preparing a polymer polyol, which is essential for creating polyurethane foam with improved physical characteristics. The stabilizer is synthesized by reacting maleic anhydride with a polyether polyol, which has an OH functionality of 3-8 and a molecular weight of 3,000-15,000. Ethylene oxide is then added to the reaction solution. The resulting stabilizer exhibits a high molecular weight of 5,000-30,000, a high OH functionality of 6-10, and a viscosity of 3,000-15,000 cps at 25°C. This innovation leads to a polymer polyol that has lower viscosity compared to previous products, thereby enhancing the physical properties of the resulting polyurethane foam.
