抄録/ポイント： ナノドメインへの制限としての結晶性重合体は,異常な結晶化挙動を示すことができる。ここで,シンジオタクチックポリプロピレン(sPP)を種々の細孔径を有するナノ多孔質アルミナテンプレートに浸透させた,それらの非等温及び等温結晶化動力学を調べた。ナノ細孔内部に位置するとして,sPPの結晶化は緩やかになった。結晶化温度は,大きなナノ細孔中のsPPに対して顕著な冷却速度依存性を明らかにした。高速冷却速度では,均一な核形成が支配的である。が,遅い冷却速度で,結晶化ピークの分割は,不均一及び均一核形成により開始された分別結晶化に起因できた。小ナノ細孔中にPPでは,均一な核形成が常に優位であり,小さい冷却速度効果を誘起した。さらに,Avramiの式及びLauritzen-Hoffman成長理論に基づいて,等温結晶化実験を,拘束下でのsPPの特性結晶化時間ははるかに長いことを示し,核密度と二次核形成速度の両方がナノ細孔に閉じ込められたsPPの減少した。Copyright 2017 Elsevier B.V., Amsterdam.
