Beschreibung
Zusammenfassung:	The present invention relates to an olefin-based polymer preparation method and an olefin-based polymer, which is prepared thereby and has excellent processability. The olefin-based polymer, which is prepared using a hybrid metallocene catalyst, according to an embodiment of the present invention, has a broad bimodal or multimodal molecular weight distribution, and thus has excellent high-speed processability, and an olefin-based polymer film manufactured by molding same has suppressed gel formation, and thus can exhibit excellent quality. La présente invention concerne un procédé de préparation de polymère à base d'oléfine et un polymère à base d'oléfine, qui est ainsi préparé et qui présente une excellente aptitude au traitement. Le polymère à base d'oléfine, qui est préparé à l'aide d'un catalyseur métallocène hybride, selon un mode de réalisation de la présente invention, présente une distribution de poids moléculaires bimodale ou multimodale large et présente ainsi une excellente aptitude au traitement à grande vitesse et un film polymère à base d'oléfine fabriqué par son moulage présente une formation de gel supprimée et peut ainsi présenter une excellente qualité. 본 발명은 올레핀계 중합체의 제조방법 및 그에 의해 제조되고 가공성이 우수한 올레핀계 중합체에 관한 것이다. 본 발명의 구현예에 따라 혼성 메탈로센 촉매의 의해 제조되는 올레핀계 중합체는 바이모달 또는 멀티모달형의 넓은 분자량 분포를 가져 고속 가공성이 우수하면서도, 이를 성형하여 제조되는 올레핀계 중합체 필름은 겔의 생성이 억제되어 우수한 품질을 나타낼 수 있다.
