| titleOfInvention | Olefin polymerization and copolymerization method |
| abstract | The present invention relates to a process for olefin polymerization and copolymerization, wherein (A) in the presence of (a) a solid complex titanium catalyst, (b) an aluminum alkyl and (c) an electron donor prepared by a production process comprising the following steps: Prepolymerization catalysts obtained by prepolymerization of olefins; (i) dissolving the magnesium halide compound in an oxygen solvent which is a mixed solvent of a cyclic ether and at least one alcohol compound to obtain a magnesium compound solution, (ii) the magnesium compound solution at -10 to 30 ° C with a titanium halide compound After the first reaction, the temperature is increased or aged to obtain particles, and then secondaryly reacted with a titanium halide compound to prepare a carrier, (iii) the carrier is reacted with a titanium halide compound and an electron donor to form a titanium supported catalyst. Preparing, (iv) washing the prepared catalyst with a hydrocarbon solvent at a temperature of 40-200 ° C., (v) reacting the washed catalyst with an aluminum compound or boron compound having two or more alkoxy groups; (B) a periodic table of Group II or Group III organometallic compounds; And (C) polymerizing or copolymerizing the olefin in the presence of an external electron donor. The olefin polymerization and copolymerization method of the present invention can provide an olefin polymer having a high stereoregularity and a wide molecular weight distribution, and has an effect of increasing the polymerization activity and increasing the productivity of the polymerization process.n n n Olefin polymerization, prepolymerization, cyclic ether, oxygen solvent, metal halide compound, solid complex titanium catalyst |
