To provide an adsorbent layer (fixed layer) that does not crack even when an adsorbent containing clay minerals is used, and provide a method using the adsorbent layer for producing a polymer compound (in particular, a charge-transporting material) with a reduced content of a low molecular weight component and of impurities such as palladium.SOLUTION: The present invention relates to an adsorbent layer composed of a mixed adsorbent containing clay minerals and non-clay minerals, with the mixed adsorbent having an angle of repose of 56° or less, and a method for producing a polymer compound with reduced impurities that comprises passing a solution of a polymer compound containing impurities through the adsorbent layer to remove the impurities.SELECTED DRAWING: None 【課題】本発明は、粘土鉱物を含む吸着剤を用いた場合でも、亀裂を発生しない吸着剤層（固定層）を提供する。また、本発明は、当該吸着剤層を用いて、低分子量成分やパラジウム等の不純物の含有量が低減された高分子化合物（特に、電荷輸送性材料）を製造する方法を提供する。【解決手段】粘土鉱物と非粘土鉱物とを含む混合吸着剤からなる吸着剤層であって、前記混合吸着剤の安息角が５６°以下である吸着剤層、及び、不純物を含む高分子化合物の溶液を、前記吸着剤層に通液して不純物を除去することを特徴とする、不純物が低減された高分子化合物の製造方法に関する。【選択図】なし
