본 발명은 불활성 분위기 하에 마그네슘, 알콜 및 혼합 할로겐화제의 환류 반응에 의하여 제조되는 생성물인 디알콕실 마그네슘 담체에 관한 것이다. 상기 혼합 할로겐화제는 요오드 및 염화마그네슘이고, 요오드 및 염화마그네슘의 중량비는 0.05:1 내지 1:0.01이다. 상기 디알콕실 마그네슘 담체는 균일한 입도 분포, 우수한 입자 형태 및 높은 벌크 밀도를 가지는 스페로이드이다. 올레핀 중합용 담체에 근거한 촉매 성분 및 촉매 또한 제공되며, 넓은 분자량 분포, 우수한 입체규칙성, 우수한 입자 형태, 및 낮은 미분 함량은 가지는 올레핀 폴리머가 얻어질 수 있다. The invention relates to a dialkoxyl magnesium carrier, which is a product produced by a reflux reaction of magnesium, an alcohol and mixed halogenated agents under an inert atmosphere. The mixed halogenated agents are iodine and magnesium chloride, and the weight ratio between iodine and magnesium chloride is 0.05:1-1:0.01. The dialkoxyl magnesium carrier is spheroid with uniform particle size distribution, excellent particle morphology and high bulk density. A solid catalyst component and a catalyst based on this carrier for olefin polymerization are also provided, and olefin polymers having a wide molecular weight distribution, good stereoregularity, excellent particle morphology and a low content of fine powders can be obtained.
