The present invention aims to provide a carrier absorbed which has significant blood component absorption capacity, especially inflammatory cytokine absorption capacity, in spite of the presence or absence of an amide group and the like, and has high solvent resistance and heat resistance. The present invention also aims to provide and a method for manufacturing the carrier absorbed. The method can introduce the desired functional group into the surface of the carrier in one process and let the aromatic rings cross-link with each other. The present invention provides a carrier absorbed which is consisted of one or more kinds of the high molecular compounds that have 2 or more repeating units comprising the aromatic ring(s) wherein the aromatic rings are covalently bonded with each other by using the structure represented by the following general formula (I).[R1 represents hydrogen or an organic group and R2 represents an organic group.]本發明的目的係在於提供一種吸附用載體,其不管醯胺基等的有無,具有顯著的血液成分吸附能力,尤其是發炎性細胞素吸附能力、且具備高耐溶劑性及耐熱性,並且提供一種吸附用載體之製造方法,其在一步驟中導入所希望的官能基至載體的表面,可將芳香環彼此交聯。本發明係提供一種吸附用載體,其包含1種以上之具有2以上的含芳香環之重複單元的高分子化合物,上述芳香環彼此係透過下述通式(I)所示的結構而共價鍵結,[R1係表示氫或有機基,R2係表示有機基]。
