Abstract

See full text

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 m2/g to 800 m2/g, preferably 280 m2/g to 600 m2/g, with one or more titanium compounds of the general formula selected from RnTi(OR′)m and (RO)nTi(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 supportwherein the supported catalyst system further comprises an alumoxane and a metallocene.
