Title:
低下されたハロゲン含量を有するポリマー組成物の製造法、ハロゲンが減少されたポリマー組成物および該組成物の使用
Document Type and Number:
Japanese Patent JP4159982
Kind Code:
B2
Abstract:
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.
