Methylene bis(diethyl malonate)-cerium ammonium nitrate redox couple serves as initiator in triethyl phosphate for polymerization of methyl methacrylate at room temperature. High polymerization yield (> 90%) can be attained at moderate concentration ratios (monomer/initiator congruent to 70:1) in 4 h reaction periods. Increasing molar ratio of methylene bis(diethyl malonate) to cerium salt causes to low molecular weights which implies possibility of its chain transfer effect through active methylene groups at the same time.
