Two series of copolymers containing disperse red 1 and methyl methacrylate have been synthesized poly4-2-acryloyloxyethylethy l amino-4-nitroazobenzene-co-methylmethacrylatepoly-DRlA-co-MMA and poly4- 2-methacryloyloxyethylethylamino-4-nitroazobenzene-co- methylmethacrylatepolyDR1M-co-MMA. The sequence distribution of the two series of copolymers is calculated on the basis of the estimated reactivity ratio values and analyzed by 13C-NMR spectroscopy. Methylmethacrylate centered triad MMD, DMD, and MMM and disperse red 1 centered triad DDD fractions are derived from the alpha-methyl carbon of MMA and carbonyl carbon in poly DR1A- co-MMA. Good agreement is found between the spectral deconvolution results and the calculated results. Polymer tacticity is analyzed with the main chain quaternary carbon and carbonyl carbon in polyDR1M-co-MMA. No spectral sequence distribution information is available for this series.
