Abstract: The 2,6-bis(2-benzimidazolyl) pyridine as a tridentate ligand for the Cu(Ⅰ) complex formation used in the initiation system of ATRP has been studied in this work. The complex obtained possesses favorable catalytic activity for the initiation of polymerization in which the ATRP characteristic is evident. Compared with the rate of polymerization initiated from Cu(Ⅰ) complex composed of different ligands with various amines, obtained results are consistent with the known order as follows: alkyl amine≈pyridind>imine>aryl amine.

Key words: 2,6-bis(2-benzimidazolyl)pyridine, atom transfer radical polymerization, Cu(Ⅰ) complex
