Abstract

본 발명은 마그네슘, 티타늄 및 할로겐으로 구성되는 올레핀 증합촉매에 있어서, 촉매의 활성을 중진시키므로써 중합 생산성을 제고시키기 위하여 티타늄 함량 조절이 용이한 전자공여체를 부가하는 동시 고활성을 유지하는 올레핀 중합촉매에 관한 것이다.In the olefin polymerization catalyst composed of magnesium, titanium and halogen, the present invention provides an olefin polymerization catalyst that maintains a high activity simultaneously by adding an electron donor that is easy to control the titanium content in order to increase the polymerization productivity by enhancing the activity of the catalyst. It is about.

종래의 올레핀 중합촉매는 중심금속의 산화 상태가 2가인 마그네슘 화합물인데 비하여 본 발명의 촉매에서는 이를 4가의 티타늄화합물로 하고 전자공여체가 히드록시기를 포함하는 지방족 불포화에스테르, 포화에스테르, 방향족에스테르중 어느 하나이거나 이들의 혼합물로하여 올레핀 증합체 생성수율을 중대시킬 수 있었다.Conventional olefin polymerization catalysts are magnesium compounds in which the oxidation state of the central metal is divalent, whereas the catalyst of the present invention is a tetravalent titanium compound and the electron donor is any of aliphatic unsaturated esters, saturated esters and aromatic esters containing hydroxy groups. By using these mixtures, it was possible to increase the yield of olefin copolymers.
