polymerization of an olefin monomer selected from (a) ethylene, (b) propylene, (c) a mixture of ethylene and propylene, and (d) a mixture of (a), (b) or (c) with at least one other alpha-olefin. In the process, the process is carried out in a polymerization reactor in the presence of a supported polymerization catalyst, wherein the supported polymerization catalyst, in powder form, with an inert hydrocarbon liquid in an amount sufficient to maintain the catalyst in powder form before being injected into the reactor. Characterized by contact. According to the process of the invention, the levels of fines associated with the polymer product, in particular fines having a diameter <125 μm and microfines of a diameter <50 μm, are reduced. |
