The solid-state condition titanium catalytic converter component for olefin polymerization, the magnesium compound and the electron donor which the suspension are done

摘要

PROBLEM TO BE SOLVED: To provide a solid titanium catalyst component for olefin polymerization from which a catalyst is obtained that has a high catalytic activity and stereospecificity, gives olefin (co)polymers having good morphology and is manufactured using a special electron donor, and an olefin polymerization catalyst and an olefin polymerization process using the catalyst.;SOLUTION: The solid titanium catalyst component for olefin polymerization contains titanium, magnesium, a halogen and an electron donor and has an average particle size d of 25-100 μm and a particle strength N (MPa) which satisfies the relation: N8,000×d^-2.;COPYRIGHT: (C)2005,JPO&NCIPI
