Supercritical fluid chromatography as a means for monitoring the preparation of macromers

Abstract

Separations by Supercritical Fluid Chromatography (SFC) yield different retentions for oligomer series depending on their end groups. This is demonstrated for oligomers from styrene and from 2-vinyl naphthalene; the end groups included hydrogen atom, hydroxyl group, oxirane ring, and diol moiety. This makes SFC a powerful tool for monitoring the preparation and subsequent reaction of oligomers of the macromer type; this is shown for some examples.
