PROBLEM TO BE SOLVED: To provide a method for removing a bleeding component and/or a bloom component from a polymer hindering observation of a polymer surface, the bleeding component and/or the bloom component mainly hydrophilic.SOLUTION: There is provided a method for removing a bleeding component and/or a bloom component in a polymer by extracting a polymer using at least one kind of amphiphilic solvent, and a phase structure observation method for a blend polymer containing two or more polymer components. The phase observation method uses an atomic force microscope and observes the blend polymer in water from which the bleeding component and/or the bloom component are removed by the method of Claim 1.SELECTED DRAWING: Figure 1 【課題】ポリマー表面の観察を困難にするブリード成分および／またはブルーム成分、主に親水性のブリード成分および／またはブルーム成分を、ポリマー中から除去する方法を提供することを目的とする。【解決手段】ポリマーを少なくとも１種以上の両親媒性溶媒により抽出することによるポリマー中のブリード成分および／またはブルーム成分の除去方法、ならびに２種以上のポリマー成分を含有するブレンドポリマーの相構造観察方法であり、請求項１記載の除去方法によりブリード成分および／またはブルーム成分を除去したブレンドポリマーを原子間力顕微鏡により水中で観察する相構造観察方法。【選択図】図１
