ABSTRACT:
Process for the preparation of an active solid hydrocarbon which can be used to polymerize olefines.
This process comprises forming a pulverulent composition by mixing a transition metal component, a porous organic or inorganic solid support and an organometallic compound of the organo-Al, organo-Mg or organo-Zn type, and polymerizing a controlled amount of one or more C.sub.2 to C.sub.12 olefines in the gas phase in contact with the pulverulent composition with a specific hourly conversion of the olefines to produce the active solid hydrocarbon.
The above active solid hydrocarbon can be used, by itself or together with an organometallic cocatalyst, as a catalytic system for polymerization of olefines, in particular in the gas phase.
