The 13C nuclear magnetic resonance spectra of MMA-EMA copolymers have been recorded and analyzed. The carbonyl carbon resonance region contains six resonating peaks due to its sensitivity to triad concentrations. From these signals, triad concentrations were determined and compared with calculated values based on Bernoullian and first-order Markovian statistics. Molecular weights were determined by viscosity measurement method.
