Abstract:
A supported catalyst composition comprising a support, at least one metallocene of 3, 4, 5 or 6 of the Periodic Table of the Elements, and at least one cocatalyst having the formula (II) ##STR6## in which R.sup.6 independently at each occurrence is identical or different and is a halogen atom or a C.sub.1 -C.sub.40 carbon-containing group,X are, independently of one another, identical or different and are each a C.sub.1 -C.sub.40 haloalkylene, C.sub.6 -C.sub.40 -arylene, C.sub.6 -C.sub.40 -haloarylene, C.sub.7 -C.sub.40 -arylalkylene, C.sub.7 -C.sub.40 -haloarylalkylene, C.sub.2 -C.sub.40 -alkenylene, C.sub.2 -C.sub.40 -haloalkynylene, C.sub.2 -C.sub.40 -alkelylene, C.sub.2 -C.sub.40 -alkenylene or C.sub.2 -C.sub.40 -haloalkenylene 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 o to 10, b is an integer from 0 to 10, c is an integer from 0 to 10n is 0 or 1,l is 0 or 1,g is 0 or 1,i is 0 or 1,j is an integer from 1 to 6, andA 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; andif a is 0 then b is 0 and the cocatalyst is neutral; if a is .gtoreq.1, then a=bc and then the cocatalyst is an anion with b cations A.sup.c+ as counterions, and where said metallocene and cocatalyst are not bonded covalently to the support.
