Title (EN) OLEFIN BLOCK COPOLYMER
(FR) COPOLYMÈRE SÉQUENCÉ D'OLÉFINE
(KO) 올레핀 블록 공중합체
Abstract: front page image
(EN)The present invention relates to an olefin block copolymer having improved processability as well as excellent elasticity and heat resistance and a preparation method thereof. The olefin block copolymer comprises first and second segments which include an ethylene- or propylene-based repeating unit and an α-olefin-based repeating unit in a different molar fraction. In a TEM (transmission electron microscope) image, the olefin block copolymer is in a form where the second segment is dispersed on the first segment as a dispersed phase having a closed curve shape.
(FR)La présente invention concerne un copolymère séquencé d'oléfine ayant une aptitude au traitement améliorée ainsi que d'excellentes propriétés d'élasticité et de résistance à la chaleur et un procédé de préparation. Le copolymère séquencé d'oléfine comprend des premier et second segments qui comprennent une unité répétitive à base d'éthylène ou de propylène et une unité répétitive à base d'alpha-oléfine suivant un rapport molaire différent. Dans une image MET (microscope électronique à transmission), le copolymère séquencé d'oléfine se présente sous une forme dans laquelle le second segment est dispersé sur le premier segment sous forme d'une phase dispersée ayant une forme courbe fermée.
(KO)본 기재는 우수한 탄성 및 내열성과 함께 향상된 가공성을 갖는 올레핀 블록 공중합체 및 이의 제조 방법에 관한 것이다. 상기 올레핀 블록 공중합체는 에틸렌계 또는 프로필렌계 반복 단위와, α-올레핀계 반복 단위를 서로 다른 몰 분율로 포함한 제 1 및 제 2 세그먼트를 포함하고, TEM (transmission electron microscope) 이미지에서, 제 1 세그먼트 상에 제 2 세그먼트가 폐곡선 형태의 분산상으로서 분산된 형태를 띠고 있는 것이다.
