Raman spectroscopy was used to investigate the kinetics of the free‐radical polymerization of methyl methacrylate in toluene, initiated with azobisisobutyronitrile at 70°C. The decrease in the intensity of the 1636 cm −1 CC stretching band compared with a solvent band as an internal standard allows an accurate determination of the rate of conversion of monomers to polymeric chains. A careful quantitative study of the evolution of the CO stretch band profile, interpreted in terms of intra‐chain dipole‐dipole interactions, gives a similar dependence for the conversion.
