METALLOCENES WITH FLUORENYL TYPE LIGANDS, METHOD OF PREPARING THEREOF, INTERMEDIATE COMPOUND FOR PREPARATION THEREOF, OLEFIN POLYMERIZATION CATALYST COMPRISING THESE METALLOGENES, AND METHOD OF POLYMERIZATION OF OLEFINS Russian patent published in 2001 - IPC

FIELD: chemical industry. SUBSTANCE: described are new metallocenes with fluorenyl type ligands of formula I: wherein R¹ is hydrogen or lower alkyl; M is Ti, Zr or Hf; R² is halogen; R³ is , wherein R⁴ is lower alkyl or C₃-C₂₀ cycloalkyl. Said metallocenes are useful as components of olefin polymerization catalysts, especially for preparing high molecular atactic polypropylene. Also described are intermediate compounds for preparing thereof, olefin polymerization catalyst comprising these meatllocenes and method of polymerzining olefins. EFFECT: improved properties of the meallocenes and more efficient preparation method thereof. 12 cl
