| titleOfInvention | Olefin polymerization or copolymerization method |
| abstract | The present invention relates to an olefin polymerization or copolymerization method, comprising: (a) a solid complex titanium catalyst prepared by the production process comprising the following steps: (1) mixing a magnesium halide compound with a cyclic ether and at least one alcohol compound Dissolving in an oxygen-containing solvent as a solvent to obtain a magnesium compound solution, (2) first reacting the magnesium compound solution with a titanium halide compound at -10 to 30 ° C, and then raising or aging to obtain particles. Reacting with a titanium halide compound to prepare a carrier; (3) reacting the carrier with a phthalic acid dialkyl ester electron donor having a titanium halide compound and an alkyl group having 9 to 13 carbon atoms to prepare a supported titanium catalyst. (4) washing the prepared catalyst with a hydrocarbon solvent at a temperature of 40-200 ° C .; (b) organometallic compounds of Groups II or III of the Periodic Table; And (c) an organosilicon compound having the general formula of (C 6 H 11 ) 2 Si (OR) 2 , wherein R represents an alkyl group having 1 to 5 carbon atoms. do. The polymer produced by the olefin polymerization or copolymerization method of the present invention has a wide molecular weight distribution by using a catalyst having excellent catalytic activity and hydrogen reactivity and having high stereoregularity, thereby increasing productivity of the polymerization process. . |
