1 H NMR spectra of poly(methyl methacrylate) prepared with benzoyl peroxide in toluene at 100 °C were measured on a 750 MHz high-resolution NMR spectrometer. End groups resulting from initiation, chain transfer, and termination reactions were assigned, and the numbers of end groups per polymer molecule were estimated. End-group signals showed splittings due to stereochemical sequences near the chain ends, the analysis of which indicated that the racemo diad at the chain end attached with C 6 H 5 − was higher than that with C 6 H 5 COO−.
