MANUFACURING METHOD OF SHAPE-CONTROLLED BLOCK COPOLYMER PARTICLE AND SHAPE-CONTROLLED BLOCK COPOLYMER PARTICLE USING THE SAME

摘要

The present invention relates to a method for producing a block copolymer capable of controlling the form of the block copolymer, and a block copolymer prepared by using the same. Preparing coalescing; Preparing an oil-in-water emulsion droplet including the block copolymer by mixing a polymer solution and an aqueous surfactant solution in which the prepared block copolymer is dissolved in an organic solvent; And an organic solvent evaporation step of forming particles in the water while controlling the evaporation rate of the organic solvent from the emulsion droplets.
