ABSTRACT:
The present invention relates to a supported composition, to processes for its preparation and to its use for polymerizing olefins. The supported catalyst composition comprises at least one transition metal compound of subgroup 3, 4 or 5 of the ##STR1## Periodic Table of the Elements and at least one cocatalyst having the formula II in which R.sup.6 independently at each occurrence are a halogen atom or a C.sub.1 -C.sub.40 carbon-containing group, X is independently at each occurrence a C.sub.1 -C.sub.40 carbon containing group, M.sup.3 independently at each occurrence is identical or different and is an element of group 13 of the Periodic Table of the Elements, a is an integer from 0 to 10, b is an integer from 0 to 10, c is an integer from 0 to 10 and a=b c, n is 0 or 1, m is 0 or 1, l is 0 or 1, g is an integer from 0 to 1, i is an integer from 0 to 1, j is an integer from 1 to 6, and A is a cation of group 1, 2 or 13 of the Periodic Table of the Elements, a carbonium, oxonium or sulfonium cation, or a quaternary ammonium cation.
