<p>Provided are a method of preparing a hollow emulsion polymer and an emulsion polymer prepared by the method. The method includes preparing a core polymer, preparing a shell polymer, and forming a hollow core by swelling the core polymer with an alkali solution. Since the swelling of hollow core formation is performed in the presence of a solvent for the core polymer and a solvent for the shell polymer, in addition to the alkali solution, hollow core destruction does not occur upon core swelling and a thin and uniform shell is obtained. The emulsion polymer thus prepared can be used as a substitute for a styrene polymer plastic pigment which is a titanium dioxide (TiO ) or organic pigment, and can be applied in aqueous paints, paper coatings, information recording papers, synthetic resins, etc.</p> |
