THE ASSIGNMENTS OF 13C-NMR SPECTRA OF HYDROLYZED POLYACRYLAMIDE

Abstract

Abstract: The structures of P(AM/AA) copolymers were determined from ¹³C-NMR spectra. Based on the observation and comparison of chemical shifts between homopolymers PAM、PAA and copolymers P(AM/AA), the assignments of the spectral lines of P(AM/AA) were established. The split peaks of carbonyl carbons in P(AM/AA) were related to the contribution of triad copolymeric sequence distribution in the molecular chains.

Key words: Polyacrylamide, Hydrolyzed polyacrylamide, NMR, ¹³C-NMR, Sequence structure, Assignment
