Abstract
The present invention discloses a continuous process and the associated system for upstaging liquid epoxy resins to produce resins with higher molecular weight. The process comprises passing continuously (i) a liquid epoxy resin having a first molecular weight, (ii) a catalyst and (iii) a compound having at least one active hydrogen or reactive functional group capable of reacting with the liquid epoxy resin in the presence of the catalyst, flow through one or more reaction chambers and under conditions effective to produce a stream comprising an upstaged epoxy resin product having a second molecular weight. The second molecular weight is higher than the first molecular weight.
