Abstract
Metallocene catalysts are organometallic coordination compounds in which one or two cyclopentadienyl rings or substituted cyclopentadienyl rings are bonded to a central transition metal atom, as shown in Figure1. The nature and number of the rings and substituents (S), the type of transition metal (M) and its substituents (R), the type of the bridge, if present, and the cocatalyst type determine the catalytic behaviour of these organometallic compounds towards the polymerization of linear and cyclic olefins and diolefins.
