Abstract
The present invention is directed to a supported catalyst composition resulting from contact of at least one transition metal catalyst precursor, such as a metallocene catalyst, and a support activator composition resulting from contact of a catalyst support (formed by reaction of a carrier, for example, an inorganic oxide (e.g., silica) and an organo halide such as bromo pentaflurobenzene in the presence of base) and a catalytic activator such as dimethylanilinium tetrakis (pentafluorophenyl) borate, and methods for making the same.
