摘要： 将以三齿2,6 双(苯并咪唑)吡啶为配体的Cu(Ⅰ)离子络合物用作A TRP引发体系的组分之一,并成功地实现了对烯类单体的自由基聚合.聚合过程具有明显的ATRP聚合特征.和几种具不同结构胺配体构成的Cu(Ⅰ)络合物的聚合速度结果相比较,本工作的结果基本符合烷基胺≈吡啶>亚胺>芳基胺的序列关系.

关键词: 2,6-双(苯并咪唑)吡啶, 原子转移自由基聚合, Cu(Ⅰ)络合物

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
