PCT No. PCT/JP96/01514 Sec. 371 Date Feb. 10, 1997 Sec. 102(e) Date Feb. 10, 1997 PCT Filed Jun. 5, 1996 PCT Pub. No. WO96/41808 PCT Pub. Date Dec. 27, 1996Ionic compounds represented by general formula (I), method of their production, olefin polymerization catalyst components, and olefin polymerization catalysts containing the components are provided. [M(R1)k(R2)1(R3)m(R4-L)n]-[D]+(I) (wherein, M is an element belonging to the Group 13; R1, R2 and R3 are pentafluorophenyl, etc., R4 is a substituted phenylene group, etc., k, l and m being each 0 or an integer of 1 to 3, and n being an integer of 1 to 4 such that k+l+m+n=4; L is trichlorosilyl, methyldichlorosilyl, dimethylchlorosilyl group, etc.; and D is a monovalent cation). The catalyst of this invention, which is used in combination with the ionic compound of this invention, a carrier, an organometal compound and a Group 4, 5 or 6 transition metal compound, has high activity so that polymerization of olefins by a slurry process, a gas phase process or the like using the catalyst gives rise to a polymer having good powder characteristics and attachment of the polymer to the reactor is minimized.
