Abstract

A supported catalyst system may include a titanated silica-containing catalyst support having at least 0.1 wt % of Ti and a specific surface area of from 150 m2/g to 800 m2/g. The Ti may be of a titanium compound 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 carbons or halogens, wherein n is 0 to 4, wherein m is 0 to 4, and wherein m+n equals 4. The supported catalyst system may include a catalyst activating agent and a metallocene. The supported catalyst system may be obtained by a process including titanating a silica-containing catalyst support with at least one vaporized titanium compound, and treating the titanated silica-containing catalyst support with a catalyst activating agent and a metallocene.
