Abstract: The present invention relates to an organic polymer adsorbent, an organic polymer adsorbent composition, and a method for preparing an organic polymer adsorbent and, more specifically, to an organic polymer adsorbent to be used for a ventilation device such as a desiccant dehumidifier. According to the present invention, an adsorbent material is changed to an organic polymer adsorbent such that the mechanical stability and durability of the material itself can be ensured, and the specific surface area of interconnected inner pores and adsorbents and the size of formed pores can be controlled since toluene is contained as a pore generator of the adsorbent. Therefore, the adsorbent of the present invention has superior adsorption performance over that of other conventional organic polymer adsorbents containing a salt-type carboxyl group and has remarkably improved desorption performance, and thus has an effect of very remarkable energy efficiency.
