| abstract |
The present invention includes a supported catalyst system prepared according to a method comprising the following steps: i) R n Ti (OR ') m and (RO) n Ti (OR') m where R and R 'are the same or different and are selected from hydrocarbyl groups and halogens having 1 to 12 carbon atoms, and n is 0 To 4, m is 0 to 4, m + n is 4, and at least one titanium compound of the general formula selected from 150 m 2 / g to 800 m 2 / g, preferably 280 m 2 / g Impregnating a silica-containing catalyst support having a specific surface area of from about 600 m 2 / g 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 alumoxane and metallocene. |
