  • Method for preparation of droplets
    Patent number: 4680320
    Abstract: A method of preparing droplets wherein a dispersion phase, insoluble or sparingly soluble in water, is injected in the form of a laminar flow into an aqueous continuous phase through an orifice. The viscosity ratio between the two phases is adjusted to a specific range to produce droplets of uniform diameter at a specified jet velocity.
    Type: Grant

    Inventors: Kyouji Uku, Shinji Kato
  • Process of continuous suspension polymerization
    Patent number: 4487898
    Abstract: A continuous suspension polymerization process for the production of polymeric particles substantially uniform particle size, entailing the steps of forming monomer droplets of substantially uniform particle size through an orifice under vibration, and effecting polymerization of the monomer droplets in an aqueous medium. The process permits carrying out polymerization without destruction or agglomeration of the monomer droplets, so that the particle size of the polymeric particles thus produced depends predominantly upon the particle size of the monomer droplets as initially formed.
