| titleOfInvention | A method for propylene polymerization or copolymerization |
| abstract | The present invention relates to a propylene polymerization or copolymerization method, and more particularly, (1) (i) a mixture of a magnesium halide compound and a group IIIA compound of the periodic table is added to a mixed solvent of a cyclic ether, at least one alcohol, a phosphorus compound and an organosilane. Dissolving to prepare a magnesium compound solution, (ii) reacting the magnesium compound solution with a transition metal compound, a silicon compound, a tin compound or a mixture thereof to precipitate solid particles, and (i) depositing the precipitated solid particles as a titanium compound. And a solid titanium catalyst obtained by reaction with an internal electron donor, (2) an organometallic compound of Group I or Group III metals of the periodic table, and (3) a nitrogen compound located in an aromatic ring as an external electron donor. In the presence of a catalyst system consisting of unsaturated nitrogen compounds in the form of substituents with steric hindrance It relates to a propylene polymerization method. According to the method of the present invention, polypropylene having excellent elasticity and ductility can be produced in high yield. |
