Components and catalysts for the polymerization of olefins |
摘要 |
Components of bimetallic catalysts for the polymerization of olefins comprising a compound of a transition metal M selected from Ti, V, Zr and Hf containing at least one M-pi bond, a compound of Ti or V not containing metal-pi bonds and a support comprising a magnesium halide. The catalysts obtained from the components of the invention are particularly suitable for gas-phase polymerization processes.
