  • Method for preparing an oil-in-water type uniform dispersion of liquid droplets and polymerization method for preparing polymer beads of uniform particle size
    Patent number: 5061741
    Abstract: A method for preparing an oil-in-water type uniform dispersion of liquid droplets, which comprises ejecting into an aqueous medium containing a dispersion stabilizer, which forms a continuous phase and moves upwards, a hydrophobic liquid having a specific gravity smaller than the aqueous medium, through a nozzle plate having a plurality of perforations capable of ejecting the hydrophobic liquid upwards, to form liquid droplets of the hydrophobic liquid in the aqueous medium, wherein a nozzle plate having a number of perforations for ejection arranged in a ring form is used as said nozzle plate, and a polymerization method for preparing polymer beads of uniform particle size, which comprises applying the method for preparing an oil-in-water type uniform dispersion of liquid droplets.
