Abstract
The carbonyl signal in the 13C NMR spectra of copolymers of methyl methacrylate and several acrylates (methyl to butyl) has been investigated to obtain detailed information on distribution of sequences in the macromolecular chain up to configurational-compositional pentads. Complementary information on distribution of even sequences can be derived from the signal of β-CH2 carbons of the main chain. Incremental calculation of the chemical shifts of the individual sequences can be performed for both carbonyl and methylene signal and permit for spectral simulation and verification of the signal attribution to the respective sequences.
