Abstract

본 발명은 폴리올레핀용 촉매원료 및 촉매성분의 개량된 제조방법이 제공되는 것으로 사염화티탄을 유기 알루미늄 화합물로 환원하는 중에 소량의 프로필렌을 존재시켜 수득한 삼염화티탄 조성물을 루이스산 또는 착화물로 처리하는 것이며, 고활성, 고입체 규칙성을 가지며 활성지속성이 높은 잇점이 있다.The present invention provides an improved method for preparing a catalyst material and a catalyst component for polyolefin, wherein the titanium trichloride composition obtained by the presence of a small amount of propylene while reducing titanium tetrachloride to an organoaluminum compound is treated with Lewis acid or a complex. It has the advantage of high activity, high stereoregularity and high activity persistence.
