Abstract

The cuboctameric silsesquioxane silanol (c-C5H9)(7)Si8O12(OH) has been applied as a model support for silica-grafted olefin polymerization catalysts. Complexes of the type Cp "[(c-C5H9)(7)Si8O13]TiX2 (Cp " = 1,3-C5H3(SiMe3)(2); X = Cl, CH2Ph) form active alpha-olefin polymerization catalysts.
