Process for Preparing Fully Crosslinked Polyacrylamide Core/Shell Beads by Precipitation Polymerization

摘要

The present invention relates to a method for producing a cross-linked polyacrylamide particles by precipitation polymerization , in more detail relates to a method for producing a spherical crosslinked polyacrylamide particles having a core / shell structure with an average particle diameter of 0.1 ~ 10 in a single step using a precipitation polymerization method . In the present invention , and have the form of particles which obtain up to form a cross-linking reaction within the particles , polyacrylamide particles are provided with a self- core / shell structure during polymerization due to the reaction ratio of the difference and the difference of affinity between the solvent monomer and , polyacrylamide particles of the present invention can significantly increase the particle size can increase the degree of crosslinking compared to the conventional polymerization method can be effectively used in various industrial fields such as high-value-added information or micro device industry .
