Abstract

본 발명은 킬레이트 4족 전이 금속 할라이드 화합물을 마그네슘-알루미늄 무기 금속 담지체에 담지시켜 제조되는 올레핀 중합용 촉매 및 그 제조방법에 관한 것이다.The present invention relates to a catalyst for olefin polymerization, which is prepared by supporting a chelate 4 group transition metal halide compound on a magnesium-aluminum inorganic metal support, and a process for producing the same.

본 발명은 올레핀 중합용 촉매는 에틸렌 및 알파 올레핀과의 공중합성이 우수하여 끈적끈적한 저중합체를 생성하지 않고 분자량 분포가 좁은 고분자량의 중합체를 생성할 수 있다.INDUSTRIAL APPLICABILITY The catalyst for olefin polymerization of the present invention is excellent in copolymerization with ethylene and an alpha olefin, so that a high molecular weight polymer having a narrow molecular weight distribution can be produced without producing a sticky low polymer.
