PRODUCTION METHOD FOR A SPHERICAL CARRIER FOR AN OLEFIN POLYMERIZATION CATALYST, AND A SOLID CATALYST USING THE SAME AND PROPYLENE POLYMERS

摘要

The provided are a method for preparing a spherical support for a catalyst for olefin polymerization and a solid catalyst prepared using the support, and a propylene polymer obtained by using the solid catalyst. Specifically, a method for preparing a spherical support which can be used for preparation of a propylene polymerization catalyst, particularly a dialkoxy magnesium support, comprising reacting metal magnesium and an alcohol in the presence of a halogenated nitrogen compound as a reaction initiator and adjusting the initial reaction temperature to the range of 20-25°C and the aging temperature to the range of 55-65°C; a solid catalyst for olefin polymerization prepared by using the above-obtained support; and a propylene polymer having a high bulk density prepared by using the above-obtained catalyst are provided.
