Atom Transfer Radical Polymerization of Secondary Amine Containing Methacrylate Monomer

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.
