Title:

PRODUCTION OF MONODISPERSE ORGANIC POLYMER BEADS

Document Type and Number:

Japanese Patent JPH04323224

Kind Code:

A

Abstract:

PURPOSE:To provide in an industrially advantageous manner the title fine polymer beads sharp in granular size distribution. CONSTITUTION:A water-insoluble organic solvent with an organic polymer dissolved therein is forced, through a membrane with fine pores, into an aqueous phase into an oil-in-water-type emulsion followed by distilling the organic solvent off, thus depositing the objective fine polymer beads with uniform granular size in the aqueous phase.
