ABSTRACT:
Process for inhibiting crust formation in reactors used for polymerising alpha-olefines, such as ethylene and propylene, in the presence of particles of catalytic solids containing titanium and chlorine in the combined state.
The polymerisation is carried out in the presence of an amount of a silicone oil which is less than 1% by weight, relative to the weight of catalytic solid.
