Abstract:
The invention covers a supported catalyst system prepared according to a process comprising the following step: i). impregnating a silica-containing catalyst support having a specific surface area of from 150 m 2 /g to 800 m 2 /g, preferably 280 m 2 /g to 600 m 2 /g, with one or more titanium compounds of the general formula selected from R n Ti(OR′) m  and (RO) n Ti(OR′) m , wherein R and R′ are the same or different and are selected from hydrocarbyl groups containing from 1 to 12 carbon and halogens, and wherein n is 0 to 4, m is 0 to 4 and m+n equals 4, to form a titanated silica-containing catalyst support having a Ti content of at least 0.1 wt % based on the weight of the Ti-impregnated catalyst support wherein the supported catalyst system further comprises an alumoxane and a metallocene.

Claim (Index 27):
The process according to  claim 18 , wherein the metallocene is selected from formula (I) or (II):\n (Ar) 2 MQ 2 \u2003\u2003(I) R\u2033(Ar) 2 MQ 2 \u2003\u2003(II) wherein the metallocenes according to formula (I) are non-bridged metallocenes and the metallocenes according to formula (II) are bridged metallocenes; wherein said metallocene according to formula (I) or (II) has two Ar bound to M which are the same or different from each other; wherein Ar is an aromatic ring, group or moiety and wherein each Ar is independently selected from the group consisting of cyclopentadienyl, indenyl, tetrahydroindenyl or fluorenyl, wherein each of said groups may be optionally substituted with one or more substituents each independently selected from the group consisting of hydrogen, halogen and a hydrocarbyl having 1 to 20 carbon atoms and wherein said hydrocarbyl optionally contains one or more atoms selected from the group comprising B, Si, S, O, F and P; wherein M is a transition metal selected from the group consisting of titanium, zirconium, hafnium and vanadium; wherein each Q is independently selected from the group consisting of halogen; a hydrocarboxy having 1 to 20 carbon atoms; and a hydrocarbyl having 1 to 20 carbon atoms and wherein said hydrocarbyl optionally contains one or more atoms selected from the group comprising B, Si, S, O, F and P; and wherein R\u2033 is a divalent group or moiety bridging the two Ar groups and selected from the group consisting of a C 1 -C 20  alkylene, a germanium, a silicon, a siloxane, an alkylphosphine and an amine, and wherein said R\u2033 is optionally substituted with one or more substituents each independently selected from the group comprising a hydrocarbyl having 1 to 20 carbon atoms and wherein said hydrocarbyl optionally contains one or more atoms selected from the group comprising B, Si, S, O, F and P.
