Study on the Resolution of Latex-State NMR spectroscopy

Abstract

Resolution and relaxation time of latex-state nuclear magnetic resonance (NMR) spectroscopy were investigated with respect to not only the mobility of the polymer but also to the movement of the dispersoid in the latex. The latex was prepared by emulsion polymerization and soap-free polymerization of butyl acrylate with peroxodisulfate. The latex-state ¹³C NMR spectra were measured with various pulse sequences that were known to be useful for the solution state ¹³C NMR spectroscopy. The high resolution latex state NMR was achieved at a temperature of more than 78 K.
