Hydrogen-transfer polymerization behavior of N-acylacrylamide

Abstract

The hydrogen-transfer polymerization of N-acylacrylamide was carried out at 120 °C for 24 h with lithium tert-butoxide (t-BuOLi) as an initiator in N,N-dimethylformamide containing N-phenyl-β-naphthylamine as a radical polymerization inhibitor. 1H NMR (nuclear magnetic resonance) spectroscopy observed a 100% conversion of the reaction mixture. 13C NMR spectrum demonstrated the selective hydrogen-transfer polymerization by the action of t-BuOLi. The peaks due to methylene and methine carbons were observed at δ35.6 and 41.7 ppm.
