Abstract

본 발명은 고체촉매 성분 및 올레핀의 예비중합체로 되며, 상기 고체촉매 성분은 (A) 입자 담체와, (B) 입자 담체(A)에 담지된 주기율표 IVB족의 천이금속 화합물과, (C) 입자 담체(A)에 담지된 유기알루미늄 옥시화합물로 구성되며, 상기 건조 예비중합된 촉매는 2.0중량% 이하 함량의 휘발성 물질을 갖는 올레핀 중합용 건조 예비중합된 촉매와; 휘발성 물질의 함량이 2.0중량% 이하가 되도록 감소시키는 불활성 가스류내에서 예비중합된 촉매를 50℃ 이하의 온도에서 건조함으로써 이 건조 촉매를 제조하는 방법을 제공한다. 본 발명의 건조 예비중합된 촉매는 유동성이 좋기 때문에 중합 반응기에 지속적으로 공급할 수 있으며, 또한 우수한 올레핀 활성을 갖는다. 예비중합된 촉매를 본 발명에 의해 건조할 경우에는 올레핀 중합의 활성을 저하하는 일이 없이 우수한 유동성의 건조예비중합 된 촉매를 제조할 수 있다.
