| titleOfInvention | Olefin Polymerization or Copolymerization Method |
| abstract | The present invention relates to a process for the polymerization or copolymerization of olefins characterized in that the olefins are polymerized or copolymerized in the presence of a catalyst system consisting of the following components (a), (b) and (c):n n n (a) a solid complex titanium catalyst comprising a magnesium compound, a titanium compound and an internal electron donor as essential components;n n n (b) organometallic compounds of metals of groups I or III of the periodic table; andn n n (c) two or more external electron donors comprising an external electron donor (1) and an external electron donor (2), wherein the external electron donor (1) comprises the solid complex titanium catalyst (a) and an organometallic compound ( Homopolymer (2) obtained by using an external electron donor (2) under the same polymerization reaction conditions as in the case of using the MFR (1) of the homopolymer (1) obtained in combination with b) and the external electron donor (1). ), The ratio of MFR (2) to MFR (2) / MFR (1) is 2 to 10, and the NMR pentad of each homopolymer (1) and homopolymer (2) is 95.5% or more. |
