Abstract: front page image
(EN)The present invention relates to an olefin block copolymer that exhibits superior elasticity and heat resistance, and to a method for preparing the copolymer. The olefin block copolymer comprises a plurality of blocks or segments containing an ethylene-based or propylene-based repeating unit and an α-olefin-based repeating unit, wherein the two units have different weight fractions. The olefin block copolymer has a density of 0.85g/cm3 to 0.92g/cm3, and a predetermined relationship between the density of X (g/cm3) and a TMA value of Y (°C) is satisfied.
(FR)La présente invention porte sur un copolymère séquencé d'oléfines qui présente une élasticité supérieure et une résistance à la chaleur supérieure et sur un procédé pour la préparation du copolymère. Le copolymère séquencé d'oléfines comprend une pluralité de séquences ou segments contenant un motif répété à base d'éthylène ou à base de propylène et un motif répété à base d'α-oléfine, les deux motifs ayant des fractions pondérales différentes. Le copolymère séquencé d'oléfines a une masse volumique de 0,85 g/cm3 à 0,92 g/cm3 et une relation prédéfinie entre la masse volumique de X (g/cm3) et une valeur de TMA de Y (°C) est satisfaite.
(KO)본 발명은 우수한 탄성 및 내열성을 나타내는 올레핀 블록 공중합체 및 이의 제조 방법에 관한 것이다. 상기 올레핀 블록 공중합체는 에틸렌계 또는 프로필렌계 반복 단위와, α-올레핀계 반복 단위를 서로 다른 중량 분율로 포함한 복수의 블록 또는 세그먼트를 포함하고, 밀도가 0.85g/cm3 ~ 0.92g/cm3이고, 밀도 X(g/cm3)와, TMA값 Y(℃)가 소정의 관계를 충족하는 것이다.
