The applications of gel permeation chromatography in the paint and allied industries. Part 3

The effects of catalysts used to promote the reaction of epoxy‐anhydride mixtures was studied by Nuss (77) using a GPC technique. It was demonstrated that when the polymerisation reaction occuring in an identical system was monitored, in the presence of different catalysts, the relationship between the apparent molecular size distribution and the lapsed time of the curing reaction was a function of the catalyst employed.
