TEMPO-mediated radical polymerization in the synthesis of poly(methyl methacrylate) macromonomer

A new synthesis of poly(methyl methacrylate) vinylterminated macromonomer is performed using the disproportionation between propagating methyl methacrylate radical and nitroxide TEMPO. The ability of the macromonomer to polymerize and copolymerize with styrene and poly(ethylene glycol) methacrylate was confirmed by GPC and isothermal calorimetry.
