A facile homogeneous polymerization system involving the iniferter agent 1-cyano-1-methylethyl diethyldithiocarbamate (MANDC) and copper(II) acetate (Cu(OAc)(2)) is successfully developed in bulk using methyl methacylate (MMA) as a model monomer. The detailed polymerization kinetics with different molar ratios (e.g., [MMA](0)/[MANDC](0)/[Cu(OAc)(2)](0) = 500/1/x (x = 0.1, 0.2, 0.5, 1.0)) demonstrate that this system has the typical "living"/controlled features of "living" radical polymerization, even with ppm level catalyst Cu(OAc)(2), first order polymerization kinetics, weight with monomer conversion and narrow molecular weight distributions for the resultant PMMA. H-1 NMR spectra and chain-extension experiments further confirm the "living" characteristics of this process. A plausible mechanism is discussed.
