| titleOfInvention |
Alpha olefin polymerization and copolymerization catalyst |
| abstract |
The present invention provides a magnesium solution by dissolving a magnesium compound in a mixed solvent of cyclic ether and two or more alcohols, and adding an organosilane thereto, and ii) recrystallizing solid particles by reacting the magnesium solution with a transition metal compound. And (iii) a solid complex titanium catalyst for olefin polymerization and copolymerization prepared by reacting recrystallized solid particles with a transition metal compound and an electron donor.n n n The catalyst of the present invention has a large particle size distribution with a large average particle size, high polymerization activity and high stereoregularity and apparent density of the resulting polymer. |
