| titleOfInvention | Olefin polymerization and copolymerization process |
| abstract | The present invention relates to an olefin polymerization and copolymerization method, comprising (A) a solid complex titanium catalyst produced by a production method comprising the following steps, (b) an aluminum alkyl and an aluminum halide, and (c) a prepolymerization catalyst obtained by prepolymerizing an olefin in the presence of an electron donor; (i) a magnesium halide compound is dissolved in an oxygen-containing solvent which is a mixed solvent of a cyclic ether and one or more alcohol compounds. Obtaining a magnesium compound solution; (ii) first reacting the magnesium compound solution with a titanium halide compound at −10 to 30 ° C., and then raising the temperature or aging to obtain particles; Reacting with a titanium halide compound to produce a support, (iii) reacting the support with a titanium halide compound and an electron donor to produce a titanium-supported catalyst, (iv) before Washing the prepared catalyst with a hydrocarbon solvent at a temperature of 40-200 ° C .; (B) a Group II or Group III organometallic compound of the periodic table; and (C) an olefin in the presence of an external electron donor. Is polymerized or copolymerized. The olefin polymerization and copolymerization method of the present invention can provide a highly stereoregular olefin polymer, and has the effect of increasing the polymerization activity and increasing the productivity of the polymerization process. |
