Characterization of complex phthalic acid/propylene glycol based polyesters by the combination of 2D chromatography and MALDI-TOF mass spectrometry.

The combination of gradient HPLC, 2D chromatography, and MALDI-TOF MS facilitated the analysis of the various distributions of phthalic acid/propylene glycol-based model polyesters. Investigations of kinetic samples taken at various reaction times highlighted the subsequent differences at various stages of the polyesterification reaction in terms of… CONTINUE READING
