Latest Patents
Hayashi's latest patents include a method for removing volatile matter from polymer solution compositions. This invention focuses on a technique for eliminating unreacted monomers and other volatile substances from a polymer solution produced from a mixture containing an aromatic vinyl monomer. The method employs two or more flash devolatilizing vessels and adjusts the solid content of the polymer solution at the outlet of the devolatilizer to exceed 97%. Additionally, it involves adding 0.5-4 parts by weight of a foaming agent to the total polymer solution composition. The process maintains the pressure of the polymer solution at 10 kg/cm or more and the temperature between 190-260°C, ultimately introducing the composition to a vapor-liquid separation vessel maintained at a vacuum of 20 Torr or less to allow foaming.
Another significant patent is related to rubber-modified styrenic resin compositions, which further showcases his expertise in polymer technology.
