Title:
RESIN PARTICLE AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH04296312
Kind Code:
A
Abstract:
PURPOSE:To obtain ionic group-containing resin particles having an arbitrary average particle diameter and a sharp particle diameter distribution and an industrial production thereof. CONSTITUTION:As ionic group-containing resin is dispersed in a micro state into an aqueous medium, a vinyl-based monomer containing a pair ionic group contained in an ionic group-containing resin is added to the dispersion and the vinyl-based monomer is polymerized so that micro dispersion state collapses by action of formed polyionic complex and micro dispersion particles of the ionic group-containing resin are joined and grown.
