Product description： Diethyl 2-bromo-2-methylmalonate acts as initiator during the atom transfer radical polymerization of methyl methacrylate. Application： Diethyl 2-bromo-2-methylmalonate was used to investigate the 1,2,2,6,6-pentamethylpiperidine as an effective reducing agent for the radical chain conversion of primary bromoesters to the corresponding esters. It was used in the synthesis of polystyrene macroinitiator via atom transfer radical polymerization.
