CATALYSTS BASED ON FULVENE METAL COMPLEXES

摘要

The invention concerns a catalyst system based on fulvene metal complexes (metallocene), which have been activated with a Lewis acid free from aluminoxan and boron, and its use for polymerising unsaturated compounds, in particular for polymerising and copolymerising olefins and/or dienes. An example for a catalyst system is: (CP*)(C5(CH3)4=CH2)ZRPH. Said complex has been activated with triisobutylaluminium (TIBA).
