Computer-Aided Characterization of the Microstructure of Methyl Methacrylate-Ethyl Acrylate Copolymers by 13 C-NMR Spectroscopy
Abstract
C-NMR spectra of methyl methacrylate-ethyl acrylate copolymers (PMMA/EA) offer sufficient resolution of the carbonyl signal to observe pentad splitting. The triad distribution can be obtained by spectral simulation, while determination of pentad distribution requires additional semi-empirical calculation of their chemical shifts.
