摘　　要：成功地合成了Co(Ⅱ)Schiff碱配合物N,N’-双(2-羟基-3,5-二甲基苯甲叉基)邻苯二胺合钴(Ⅱ),并以其替代经典原子转移自由基聚合(ATRP)中的“Cu(I)X/配位剂”催化甲基丙烯酸甲酯(MMA)进行均聚,制得了分子量分布较窄的聚合物.于40℃研究了聚合反应动力学,进一步证实反应具有一定程度的可控特征.此外,实验还证实该亚钴配合物兼具引发功能.A kind of Co( I ) Schiff base complex, [N, N'-1, 2-PhenylenediamineBis (2-hydroxy-3,5-dimethylphenylmethylidene-iminato)] cobalt( Ⅱ ), was successfully synthesized. The complex was then used, in place of 'Cu( I )X/ligand' in a typical atom transfer radical polymerization (ATRP), to catalyze the hompolymerization of methyl methacrylate (MMA); polymers with relatively narrow molecular weight distributions were obtained. Investigation on the kinetics at 40 C showed some controlled featurews for the polymerization. Besides, the co (Ⅱ) complex was confirmed to possess the function of initiating as well.
