Title (EN) CYCLIC OLEFIN RESIN COMPOSITION FOR MOLDING, MOLDED BODY, AND RESIN
(FR) COMPOSITION DE RÉSINE D'OLÉFINE CYCLIQUE POUR MOULAGE, CORPS MOULÉ ET RÉSINE
(JA) 成形用環状オレフィン系樹脂組成物、成形体および樹脂
Abstract:
(EN) Provided are: a cyclic olefin resin composition for molding, the composition containing a resin (A) which has a structural unit (a1) derived from α-olefin and a structural unit (a2) derived from cyclic olefin, has glass transition points in both a 50°C or lower region and a 125°C or higher region as measured by differential scanning calorimetry, and has a degree of dispersion in the range of 1.0-1.6 as measured by gel permeation chromatography; and a molded body produced from this composition. Also provided is a resin (A) which has a structural unit (a1) derived from α-olefin and a structural unit (a2) derived from cyclic olefin, has glass transition points in both a 50°C or lower region and a 125°C or higher region as measured by differential scanning calorimetry, and has a degree of dispersion in the range of 1.0-1.6 as measured by gel permeation chromatography.
(FR) L'invention concerne : une composition de résine d'oléfine cyclique pour moulage, la composition contenant une résine (A) qui a une unité structurale (a1) dérivée d'une α-oléfine et une unité structurale (a2) dérivée d'oléfine cyclique, présente des points de transition vitreuse situés dans une région inférieure ou égale à 50 °C et une région supérieure ou égale à 125 °C, tels que mesurés par analyse calorimétrique à compensation de puissance, et présente un degré de dispersion dans la plage de 1,0 à 1,6, tel que mesuré par chromatographie sur gel ; et un corps moulé produit à partir de cette composition. L'invention concerne également une résine (A) qui a une unité structurale (a1) dérivée d'une α-oléfine et une unité structurale (a2) dérivée d'oléfine cyclique, présente des points de transition vitreuse situés dans une région inférieure ou égale à 50 °C et une région supérieure ou égale à 125 °C, tels que mesurés par analyse calorimétrique à compensation de puissance, et présente un degré de dispersion dans la plage de 1,0 à 1,6, tel que mesuré par chromatographie sur gel.
(JA) α-オレフィンに由来する構造単位(a1)と、環状オレフィンに由来する構造単位(a2)とを有し、示差走査熱量測定を行ったときに50℃以下の領域と125℃以上の領域の両方にガラス転移点があり、かつ、ゲルパーミエーションクロマトグラフィーで測定した分散度が1.0~1.6の範囲にある樹脂(A)を含有する、成形用環状オレフィン系樹脂組成物。また、この組成物からなる成形体。また、α-オレフィンに由来する構造単位(a1)と、環状オレフィンに由来する構造単位(a2)とを有し、示差走査熱量測定を行ったときに50℃以下の領域と125℃以上の領域の両方にガラス転移点があり、かつ、ゲルパーミエーションクロマトグラフィーで測定した分散度が1.0~1.6の範囲にある樹脂(A)。
