<p>A process for producing olefin polymers, which comprises the steps of polymerizing an olefin monomer in a polymerization zone in the presence of a catalyst comprising a transition metal compound to form an olefin polymer, and adding at the end of or downstream from the polymerization zone a composition having a weight averaged molecular weight of at least 100 and containing a group R, a cation Y, an anionic group -C(R1)2-X-, and optionally a group -C(R1)2-X-H, the composition having a relative mole fraction n of cations Y and a relative mole fraction m of group -C(R1)2-X-H, wherein 0<n<=1, 0<=-m<1, and n+m=1. Use of such a composition for rendering inert undesired quantities of acidic compounds or halogen-containing compounds present in an olefin polymer by mixing the olefin polymer intimately with the additive composition.</p> |
