Ethylene/1-hexene copolymerization with a novel SiO2-supported hybrid chromium-based catalyst is investigated. This catalyst is prepared using the residual surface hydroxyl groups in Phillips catalyst to support bis(triphenylsilyl) chromate in order to attain the merits of two important chromium-based catalysts, namely inorganic Phillips and organic S-2 catalysts. The copolymer shows better short chain branch distribution.
