Citric acid/glycerol ester, a backup of 2, 2-bis (hydroxymethyl) propionic acid and biobased synthesis of anionic polyurethane dispersion
S Morang, N Biswakarma, RC Deka, N Karak - Progress in Organic …, 2022 - Elsevier
Nowadays biobased anionic polyurethane dispersions (PUDs) have been widely used in
automotive, paints, coatings etc., but the strategies for achieving optimum properties are still
highly challenging. Contrary to current knowledge, here glycerol ester of citric acid (GECA)
was used as an internal biobased emulsifier for preparing high performance anionic PUD.
Density functional theory (DFT) calculations revealed that GECA has comparable reactivity
to the conventional bis (hydroxymethyl) propionic acid. GECA was prepared by an …
