Catalyst and process for polymerizing alpha-olefins |
| abstract |
An active catalyst in the polymerization of alpha-olefins is obtained by: (i) bringing a dialkyl magnesium, or an alkyl magnesium halide into contact with a silicon or tin halide, in solution in an inert organic solvent, until a granular solid precipitates off; (ii) suspending said solid precipitate in an inert organic solvent and bringing it into contact with a compound which can be defined by the formula: <CHEM> wherein M represents a metal from Group IVB of the Periodic Table of Elements, and each R and Cp has the meaning as reported in the disclosure, in order to form a granular solid catalyst; and (iii) recovering said solid catalyst from the resulting suspension. |
