Abstract:
(EN) The present invention relates to a method for preparing an olefin-based polymer, comprising a step of polymerizing an olefin-based monomer in the presence of a catalytic composition comprising cis-isomers and trans-isomers of a transition metal compound. According to the method for preparing the olefin-based polymer in accordance with one embodiment of the present invention, it is possible to obtain a similar level of density and molecular weight compared to a conventional polymer by using a relatively lower amount of octene, compared to the amount of octene used in conventional polymer preparation, and thus it is possible to prepare an olefin-based polymer which has a more excellent copolymerization property and is more stable.
(FR) La présente invention concerne un procédé de préparation d'un polymère à base d'oléfine, comprenant une étape de polymérisation d'un monomère à base d'oléfine en présence d'une composition catalytique comprenant des isomères cis et des isomères trans d'un composé métallique de transition. Selon le procédé de préparation du polymère à base d'oléfine conformément à un mode de réalisation de la présente invention, il est possible d'obtenir un niveau similaire de densité et de masse moléculaire par rapport à un polymère classique à l'aide d'une quantité relativement plus faible d'octène, par rapport à la quantité d'octène utilisée dans la préparation du polymère classique, et il est ainsi possible de préparer un polymère à base d'oléfine qui présente une propriété de copolymérisation encore plus excellente et est plus stable.
(KO) 본 발명은 전이금속 화합물의 시스(cis) 이성질체 및 트랜스(trans)이성질체를 포함하는 촉매 조성물의 존재 하에, 올레핀계 단량체를 중합하는 단계를 포함하는 올레핀계 중합체의 제조방법에 관한 것이다. 본 발명의 일 실시예에 따른 올레핀계 중합체의 제조방법에 따르면, 종래의 중합체 제조시 사용한 옥텐양에 비해 상대적으로 적은 옥텐양으로 종래의 중합체와 유사 수준의 밀도와 분자량을 나타낼 수 있어 공중합성이 더 우수하며, 더욱 안정한 올레핀계 중합체를 제조할 수 있다.
