Abstract
Acrylic oligomers such as pentaerythritolacrylates (PEA), which are often utilized in the field of functionalized materials, generally consist of very complex homologous series. In this work, measuring conditions for packed-column supercritical fluid chromatographic separation of a complex PEA sample manufactured industrially were systematically examined using temperature programming or modifier gradient technique. Under the conditions thus optimized, not only the main components, PEA homologues containing different number of acryloyl groups, but also trace constituents such as their by-products formed through Michael addition reactions were favorably resolved on the resulting chromatograms. The fact that the coefficient of variation (CV) for relative intensity of each peak was approximately 3–6% even for the minor components suggested that detailed compositional analysis of PEAs could be performed precisely by the proposed method.
