Abstract
본 발명은 입체 규칙성이 높고, 중합체 성상이 양호한 폴리올레핀 중합용 촉매 조성물을 제공하는 것으로, 무할로겐 유기 마그네슘 화합물, 티탄할로겐 화합물, 그리고 유기 규소 화합물을 필수 성분으로 하여 제조한 티탄계 촉매에 유기금속 화합물, 전자 공여체인 유기산 에스테르 및 유기규소 화합물을 단독 또는 2종 이상 혼합시켜 구성되며, 이를 이용하여 중합시에는 수율이 높아 중합물에 잔류하는 촉매를 제거하는 공정이 필요없고, 중합체의 성상이 양호하게 된다.The present invention provides a catalyst composition for polymerizing polyolefins having high stereoregularity and good polymer properties. The present invention relates to organometallic catalysts in titanium catalysts prepared using halogen-free organic magnesium compounds, titanium halogen compounds, and organosilicon compounds as essential components. Compounds, organic acid esters and organosilicon compounds, which are electron donors, are mixed alone or in combination of two or more.The polymerization yields high yields and eliminates the need to remove catalysts remaining in the polymers. do.
