Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress aggregation of pellet each other by fusion during manufacturing an ethylene-vinyl ester-based copolymer saponified product (EVOH) pellet with an aliphatic acid amide-based lubricant adhered to a surface.SOLUTION: There is provided a method for manufacturing an EVOH pellet with an aliphatic acid amide-based lubricant adhered to a surface, having a process for adjusting a surface temperature of the EVOH pellet of 130°C or less and a process for scattering an aqueous dispersion of the aliphatic amide-based lubricant to the EVOH pellet.SELECTED DRAWING: None 【課題】脂肪酸アミド系滑剤が表面に付着したエチレン−ビニルエステル系共重合体ケン化物（ＥＶＯＨ）ペレットを製造する際に、ペレット同士が融着して塊となることを抑制する。【解決手段】脂肪酸アミド系滑剤が表面に付着したＥＶＯＨペレットを製造する方法であって、ＥＶＯＨペレットの表面温度を１３０℃以下に調節する工程と、前記ＥＶＯＨペレットに、脂肪酸アミド系滑剤の水分散液を散布する工程と、を有することを特徴とする。【選択図】なし
