Abstract
AbstractTwo kinds of SiO2‐supported Cp*TiCl3 (Cp* = η5‐1,2,3,4,5‐pentamethylcyclopentadienyl) catalysts were prepared, using SiO2 modified with 3‐aminopropyltrimethoxysilane (NSiO2) and the ordinary SiO2 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 NSiO2 supported Cp*TiCl3 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.
