摘要： The present invention provides a method for removing unreacted monomer in polymer using a SCC comprising a housing having a rotation axis; a supply part of at least one polymer formed inside of the housing; at least two spinning cones that are installed so as to have a constant gradient from the upper part to the lower part to the rotation axis, move polymer supplied through the polymer supply part, and rotate around the rotation axis; a fixed cone that is fixed and formed on the inner side of the housing, and provides a pathway for sequentially moving polymer from a spinning cone at the upper part to a spinning cone at the lower part; a product collection part for collecting polymer moved through the spinning cone and the fixed cone; and a driving part for rotating the spinning cone. The method for removing unreacted monomers in polymer using SCC according to the present invention may control polymer residence time and thus does not lower polymer stability even under high temperature condition, and has high area density and thus has excellent unreacted monomer removal efficiency without using steam and the like, or with a small amount of steam, and the like.
