Microstructure of copolymers of two methacrylate monomers are difficult to analyze by 13C NMR spectroscopy since the region of the carbonyl signals, usually utilized for this purpose, is relatively narrow and the lines split due to different sequences are strongly superimposed. The spectra of the two respective homopolymers indicate that both monomers introduce configurational effects, hence the copolymer microstructure should be described in terms of distribution of configurational-compositional sequences. It was shown that for the investigated copolymer of n-butyl methacrylate and methyl methacrylate such analysis can be performed at the triad level.
