Abstract:

EPON 828 samples manufactured in Australia, Canada, the United Kingdom, and the United States are analyzed using gel permeation chromatography GPC and reverse bonded-phase high performance liquid chromatography HPLC. Variations in resin composition are monitored and quantitatively analyzed. Molecular weights calculated from GPC data are in close agreement with values determined by vapor phase osmometry. Differences in chemical composition are much more apparent when the resins are monitored using the HPLC method than by GPC. The results of the analyses and limitations of the methods are discussed.
