Title:
METHOD FOR PRODUCING SOLID CATALYTIC COMPONENT FOR OLEFIN POLYMERIZATION, CATALYST FOR OLEFIN POLYMERIZATION, METHOD FOR PRODUCING CATALYST FOR OLEFIN POLYMERIZATION, AND METHOD FOR PRODUCING OLEFIN POLYMER
Document Type and Number:
WIPO Patent Application WO/2022/004205
Kind Code:
A1
Abstract:
Provided is a method for producing a solid catalytic component which is for olefin polymerization and is obtained by a production method using an organic solvent other than an aromatic hydrocarbon, and which, when provided for the polymerization of olefins, enables a polymer having excellent balanced properties such as processability or crystallinity to be produced under high polymerization activity, like a solid catalytic component for olefin polymerization produced by using an aromatic hydrocarbon. The method for producing a solid catalytic component for olefin polymerization is characterized in that a solid catalytic component for olefin polymerization is obtained by bringing dialkoxy magnesium, a tetravalent titanium halogen compound, and an internal electron-donating compound into contact with each other in an inert organic solvent containing an alicyclic hydrocarbon compound.
