Abstract: The present invention relates to a dry absorbent for capturing an acid gas and a producing method thereof. According to the present invention, the dry absorbent containing amine with a high density can be produced in an easy manner by polymerizing monomers containing a large amount of amine, which is a functional group and can effectively capture an acid gas. The dry absorbent not only has a polymer structure in which the distribution, location, and number of the amine groups in a polymer structure can be controlled but also absorbs a large amount of carbon dioxide by containing a large amount of amine, which easily absorbs carbon dioxide. Moreover, the monomers containing amine groups are bound by covalent bonds to the surface of a support, resulting in an outstanding chemical stability. Therefore, an initial absorption amount of the dry absorbent can be maintained even after repeated absorption and desorption of carbon dioxide and thus the dry absorbent can be used as a dry absorbent for capturing an acid gas.
