Chemistry International, Round-Robin Test on the Molecular Characterization
of Epoxy Resins by Liquid Chromatography
Epoxy resins are an important group of synthetic resins with many application
areas. Thus far, only relatively primitive analytical tests have been
used for routine characterization of epoxy resins. The simple characteristics
are often unable to discriminate between different samples, to find
structure vs. properties relations, and to evaluate production reproducibility.
Liquid-chromatographic characterization of epoxy resins has been reported
in the literature, but no standard procedure has been established and
no systematic study of the results obtained in different laboratories
has been reported.
IUPAC has approved a project to run a round-robin test on the analysis
of epoxy resins by liquid chromatography. Two different samples of solid
bisphenol A-based epoxy resins are intended to be analyzed by conventional
size exclusion chromatography (SEC), SEC coupled with a light-scattering
detector or a viscometer, and high-performance liquid chromatography
(HPLC). Participants in the test can choose to employ only one of the
methods mentioned or to use all of them. Participants from research
as well as production plant laboratories are welcome, and the requirements
for the samples should be addressed to Martin Kaska, SYNPO, S. K. Neumanna
