Abstract
Size exclusion chromatography of small molecules has been investigated with high efficiency columns of crosslinked polystyrene. Performance evaluations and calibrations have been determined in toluene and in tetrahydrofuran, and the effect of the solvents on solute retention is discussed. Oligomer separations of samples obtained in the thermal degradation of several polymeric materials are reported, and the utility of the technique for polymer degradation studies is clearly evidentiated.
