Abstract

Two kinds of SiO~2~‐supported Cp^*^TiCl~3~ (Cp^*^ = η^5^‐1,2,3,4,5‐pentamethylcyclopentadienyl) catalysts were prepared, using SiO~2~ modified with 3‐aminopropyltrimethoxysilane (NSiO~2~) and the ordinary SiO~2~ as the carrier. The copolymerization of ethylene and 1‐octene was conducted over them combined with methylaluminoxane (MAO) as cocatalyst. From a detailed analysis of the produced copolymers, it was found that the NSiO~2~ supported Cp^*^TiCl~3~ catalyst gives poly(ethylene‐co‐1‐octene) with a higher content of 1‐octene and a narrower molar mass distribution as well as a narrower chemical composition.

Using BF 3 as probe, the surface of SiO 2 was probed. The effects of the roast temperature on the SiO 2 surface were investigated and a possible mechanism is suggested. Using SiO 2 as starting material for supports, new supported catalysts for copolymerization of ethylene and propylene were prepared
