聚(4-甲基丙烯酰氧基-2,2,6,6-四甲基哌啶氮氧自由基)(PTMA)是一种具有应用前景的锂离子电池正极材料, 一般通过2,2,6,6-四甲基哌啶醇-4-甲基丙烯酸酯(TMPM)的自由基聚合及进一步氧化来制备. 但是TMPM的可控自由基聚合受制于其分子中的仲氨基团. 通过对不同的引发剂和催化体系TMPM的原子转移自由基聚合(ATRP)进行了研究, 得到了TMPM最优的ATRP聚合条件, 为合成具有不同分子量或拓扑结构的自由基聚合物奠定了基础.

Radical polymer poly(2,2,6,6-tetramethylpiperidinyloxy-4-yl methacrylate) (PTMA), a potential cathode materials, was prepared by radical polymerization of 2,2,6,6-tetramethylpiperidin-4-yl methacrylate (TMPM) containing secondary amine group, followed by oxidation into radical polymer. However, the living radical polymerization of TMPM was hindered by its secondary amine group. The optimized atom transfer radical polymerization condition for TMPM via screening various initiators and catalyst systems was reported, and poly(2,2,6,6-tetramethylpiperidin-4-yl methacrylate)s with different molecular weight were prepared.

Key words: methacrylate, secondary amine, atom transfer radical polymerization
