CATALYST-ON-CARRIER COMPONENT, CATALYST ON CARRIER, ADDUCT USED AS OLEFIN POLYMERIZATION CATALYST, AND METHOD FOR POLYMERIZATION OF OLEFINS Russian patent published in 2000 - IPC

FIELD: polymerization catalysts. SUBSTANCE: invention provides new catalyst-on- carrier component containing (i) carrier material consisting of silica and alumoxane or trihydrocarbylaluminum compound with general formula A1R1x

, in which each R¹, independently from each other, is C2-C20-hydrocarbyl radical and x = 3, and (ii) activating compound including Broenstead acid cation capable of interacting with transition metal metallocene compound to form transition metal complex, which is catalytically active for polymerization of olefins, and a compatible anion with up to 100 nonhydrogen atoms containing at least one substituent including group with active hydrogen and depicted by general formula , wherein M' is boron, Q, independently in each case, is substituted C1-C20-hydrocarbyl, G is (r+1)-valent hydrocarbon radical linked to M', T is oxygen atom, m integer from 1 to 7, and n integer from 0 to 7. EFFECT: increased catalytic activity. 17 cl, 1 tbl, 29 ex
