Abstract
A catalyst for olefin polymerization obtainable by contacting: PA1 (a) a transition metal compound containing a transition metal of the Group 4 of the Periodic Table, PA1 (b) an organometallic compound, and PA1 (c) a solid catalyst component comprising a carrier and an ionized ionic compound capable of forming a stable anion on reaction with a transition metal compound, wherein the ionized ionic compound comprises a cationic component and an anionic component and the cationic component is fixed on the surface of the carrier. The catalyst system of the invention enables production of olefin polymers with excellent physical properties at good productivity without causing contamination of a polymerization vessel.
