Abstract
The 1H and 13C nuclear magnetic resonance spectra of poly(acrylamide) (PAA) in D2O at a temperature of 343 K were analyzed by two-dimensional NMR (2D NMR) methods including 1H J-resolved spectroscopy, F1-axis (1H) broad-band decoupled correlation spectroscopy, and 1H broad-band decoupled 13C–1H chemical shift correlation spectroscopy. Combined use of these 2D NMR methods provided absolute assignments of 1H and 13C spectra at the triad–tetrad level. At the pentad–hexad level, the 13C spectra were assigned by the aid of spectral simulation. The polymerization of PAA proceeds in a Bernoulli-trial process with Pm=0.45.
