Vinyl alcohol → Polyethylene glycol monolaurate

Participants

Reaction Steps

Comparative experiments were carried out in which in place of N-octadecyl gluconamide, the suspension stabilizers Gohsenol KP 08, Armotan® MP (sorbitan monopalmitate), Armotan® ML (sorbitan monolaurate) Tween® 20 (polyoxyethylene (20) monolaurate) and Tween® 21 (polyoxyethylene (4) monolaurate) were used. Only the results obtained with Tween® 21 (polyoxyethylene (4) monolaurate) compared with those obtained with N-octadecyl gluconamide. When only Gohsenol KP 08 was used, the results obtained were distinctly poorer. In all other cases destabilization of the suspension was observed after 1 to 2 hours polymerization.
