摘要
Provided is a method for preparing monodisperse copolymer particles, wherein the prepared particles are stabilized spheres, have better physical properties than those of existing polystyrenic particles, and are usable as conductive balls for ACF, spacers, column fillers, etc. The method for preparing monodisperse copolymer particles consists of preparing spherical copolymer particles by anionic dispersion polymerization using a monomer, a comonomer, a stabilizer, a dispersing solvent, and an anion polymerization initiator. The prepared copolymer particles have an average particle diameter of 1micron or larger, and a particle size distribution(Dw/Dn, wherein Dn is a number average particle diameter and Dw is a weight average particle diameter) of less than 1.5.
