Abstract High performance size exclusion (HPSEC) and high resolution reversed phase liquid chromatographic (HPLC) methods are described for the analysis of methylated melamine-formaldehyde resins. Monomer, oligomer and polymer components of a resin were isolated by HPSEC. The molecular weights of components within each HPSEC fraction were determined by fast atom bombardment/mass spectrometry (FAB/MS). The HPSEC fractions were also analyzed by HPLC and their chromatograms compared to the whole resin HPLC chromatogram. Based on the elution time of the major component, hexakis (methoxymethyl) melamine, and on comparison with a different resin having a lower degree of methylation, it is possible to assign tentative structures to all major HPLC peaks.
