More Information
Summary:The present invention relates to a hybrid-supported metallocene catalyst and a preparation method of a polyolefin using the same, and more specifically, to a hybrid-supported metallocene catalyst which can prepare a polyolefin without a sharp decrease in catalyst activity even during a polymerization process using a multi-stage reactor by increasing the stability of the catalyst and a preparation method of a polyolefin using the same. 본 발명은 혼성 담지 메탈로센 촉매 및 이를 이용한 폴리올레핀의 제조방법에 관한 것이다. 보다 구체적으로, 촉매의 안정성을 증가시켜 다단 반응기를 사용하는 중합 공정시에도 촉매 활성의 급격한 저하없이 폴리올레핀을 제조할 수 있는, 혼성 담지 메탈로센 촉매 및 이를 이용한 폴리올레핀의 제조방법에 관한 것이다.
