Latest Patents
Yagyu's latest patents include a "Process and apparatus for suspension polymerization." This invention provides an apparatus designed to produce polymer particles with uniform sizes. The apparatus features a droplet forming device equipped with at least one orifice and a recycle line that circulates the aqueous dispersion medium through the droplet forming device, a first reactor, and a second reactor. This innovative design allows for the production of polymer particles with consistent particle sizes.
Another significant patent is the "Process for suspension polymerization." This process involves several steps, including applying regular vibration to a flow of monomer liquid, introducing the aqueous dispersion medium containing droplets into a first reactor, and partially polymerizing the monomer liquid. The process ensures that the specific gravity of the droplets remains less than that of the aqueous dispersion medium, maintaining their suspended condition. The partially polymerized droplets are then transferred to a second reactor for further polymerization.
