Summary:PROBLEM TO BE SOLVED: To provide a process for inhibiting polymerization of (meth)acrylic acid and/or (meth)acrylic ester.SOLUTION: The present invention provides a process for inhibiting polymerization of (meth)acrylic acid and/or (meth)acrylic ester by introducing an oxygenous gas into the (meth)acrylic acid and/or the (meth)acrylic ester, in which the (meth)acrylic acid and/or the (meth)acrylic ester has a degree of purity of at least 95% and is in the liquid flocculation state.SELECTED DRAWING: None 【課題】（メタ）アクリル酸および／または（メタ）アクリル酸エステルの重合を防止する方法を提供する。【解決手段】酸素を含有するガスを、（メタ）アクリル酸および／または（メタ）アクリル酸エステルに導通することにより（メタ）アクリル酸および／または（メタ）アクリル酸エステルの重合を防止する方法であって、（メタ）アクリル酸および／または（メタ）アクリル酸エステルが、少なくとも９５％の純度を有しており、かつ液状の凝集状態で存在することを特徴とする。【選択図】なし
