Ch. Zhang et al., SYNTHESIS OF HYDROGENATED OLIGO(ISOPRENE)CARBOXYLIC ACID N-ALKANOLAMIDES - A NEW GROUP OF NONIONIC SURFACTANTS, Journal of dispersion science and technology, 17(5), 1996, pp. 455-458
Uniform hydrogenated oligo(isoprene)carboxylic acid N-alkanolamides we
re prepared in high yields by living anionic oligomerization of isopre
ne, followed by carboxylation with dry ice, hydrogenation, then amidat
ion with several commercial alkanolamines.
