| titleOfInvention | Spheroidal particles for olefin polymerization catalyst |
| abstract | The present invention relates to a process for the preparation of a circular magnesium alkoxide having improved mechanical strength and a uniform particle size distribution, characterized in that it comprises heating in the range of 40 to 65 占 폚 for 2 hours and then heating at 65 to 80 占 폚 for 1 hour, The magnesium metal is reacted with the alcohol mixture in an iodine atmosphere and the reaction is maintained at 80 DEG C for an additional 6 to 10 hours and the resulting gas produced during the reaction is condensed using an overhead condenser , Discharging the hydrogen gas produced during the reaction, and filtering and reusing the remaining alcohol mixture after the reaction. The present invention also relates to a polymer resin produced using a Ziegler-Natta catalyst and a precatalyst produced using spherical magnesium alkoxide particles and an alkoxide prepared by the above method. |
