“…Therefore, in a certain range of molecular weight, these parameters might be used to predict the elution time of other PSt homopolymers. 34 Moreover, it should be reasonable to infer that the similar elution behavior under same elution conditions can be regarded as an indication of the presence of analogous polymer segments. 12,15 This conclusion has also been confirmed by the chromatogram of the PSt 1 prepared with BDB.…”

“…Therefore, gradient methods are applied frequently, if samples containing molecules of different chemical composition need to be separated. Gradient chromatography has been applied to separate blends, − graft, − or block ,− copolymers into the individual components. For statistical copolymers gradients were applied to separate the chains of different chemical composition, ,− which allows obtaining the chemical composition distributions of such polymers.…”

The development of a chromatographic method capable to separate poly(methyl methacrylate-stat-methacrylic acid) samples with methacrylic acid contents of up to 50% by chemical composition is described. For this purpose a gradient ranging from chloroform to dimethylacetamide on a PSS PROTEEMA column was applied. The application of a conventional gradient resulted in severe breakthrough peaks. Therefore, the recently developed concept of SEC gradients was used. No breakthrough peaks were observed, and the peaks corresponding to samples of different content of methacrylic acid were well resolved. A nearly linear relationship between elution volume and methacrylic acid content was observed. The developed method allows determination of the chemical composition distribution of the abovementioned class of polymers.

A comprehensive two-dimensional liquid chromatography system was developed to precisely describe the molecular heterogeneity of fatty alcohol ethoxylates. The end-group functionality was analyzed by gradient HPLC while ethylene oxide oligomer distributions were characterized by liquid adsorption chromatography. A baseline separation of all functionality fractions irrespective of the ethylene oxide oligomer chain length was achieved on nonpolar X-Terra C(18) with a methanol-water gradient, whereas an isocratic flow of isopropanol-water on a polar Chromolith Si column gave a separation according to the oligomer chain length without interference of the end-group distribution. The combination of these two methods to conduct online two-dimensional liquid chromatography experiments resulted in a comprehensive two-dimensional picture on the molecular heterogeneity of the sample.
