ADDITIVE FOR RENDERING INERT ACIDIC OR HALOGEN-CONTAINING COMPOUNDS CONTAINED IN OLEFIN POLYMERS

摘要

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(R<1>)2-X<->, and optionally a group -C(R<1>)2-X-H, the composition having a relative mole fraction n of cations Y and a relative mole fraction m of group -C(R<1>)2-X-H, wherein 0
