Latest Patents

Takeshi Sumita's latest patents focus on innovative polymer/polyol compositions. One of his patents describes a process for creating polymer/polyol compositions by polymerizing an ethylenically unsaturated monomer in situ in a polyol. This method utilizes an inner-olefin containing at least five carbon atoms, resulting in lower viscosity and improved properties for the resulting polyurethanes. Another patent outlines a similar process but incorporates an azo compound and a peroxide with a half-life period temperature that is at least 10 degrees Celsius lower than that of the azo compound. This innovation enhances stability even at higher styrene content. His work also includes polymer/polyol compositions that involve polymerizing ethylenically unsaturated monomers, which afford polyurethanes with improved characteristics.
