Summary Several different oligomers containing polar groups either in the backbone or in the side chains were successfully separated by SFC on polystyrene stationary phases. Composition gradient elution was used, the mobile phase components being CO2 and acetonitrile or CO2 and methanol. Among the oligomers separated were poly(ethylene oxide)s, poly(caprolactone), epoxy prepolymers and poly(2-vinylpyridine). The use of CO2/acetonitrile made possible the detection of ether groups at 190 nm.
