Abstract: Process for producing an olefin polymer of a low polydispersity index having low catalyst residues and low chlorine content, by polymerizing olefins in solution in the presence of a cationic catalyst, in a reactor containing a liquid phase comprising a liquid boiling hydrocarbon polymerization medium and having a vapor space above the liquid phase. The polymerization is carried out in the presence of a non-mechanical agent capable of suppressing foam formation during the polymerization.
