Реферат:
Reactive species in SiO2-supported, zirconocene-based olefin-polymerization catalysts have been characterized by comparison of their UV-vis spectra with those of related, NMRspectroscopically identified catalyst species in homogeneous solution. Neutral zirconocene dihydride complexes are found to arise in hydrocarbon solutions as well as on SiO2 supports when catalyst systems that contain rac-Me2Si(ind)2ZrCl2 and methylaluminoxane (MAO) are modified by addition of diisobutylaluminum hydride or triisobutylaluminum. These complexes,
tentatively formulated as adducts with Lewis-acidic alkylaluminum species AlR2X, racMe2Si(ind)2ZrH2
{nAlR2X}, are reconverted into the initial reactive zirconocene cations upon addition of isobutene to these reaction systems
