摘要：
Polymer compositions with reduced living halogen content are used as additive to lubricating oils and are prepared by polymerizing at least one ethylenically unsaturated monomer using a) at least one initiator containing a transferable halogen and b) one or more metal catalysts containing at least one transition metal, in the presence of ligands which can form a coordination compound with the one or more metal catalysts, to obtain a polymer composition having a living halogen content, and after the polymerizing, reacting the polymer composition having a living halogen content with at least one organic nitrogen compound in the presence of a nonpolar solvent, thereby reducing the living halogen content to obtain the polymer composition having a reduced halogen content.
