WebJun 10, 2011 · Provided is a preparation method of bisphenol A liquid epoxy resin. The preparation method comprises dissolving bisphenol A and epichlorohydrin, and under the conditions of 45-65 DEG C, adding a cocatalyst and NaOH solution to perform etherification for 1-3h; under the conditions of 55-70 DEG C and absolute pressure of 15-25KPa, … WebUnlike bisphenol A, bisphenol F is a mixture of isomers rather than a discreet compound. Bisphenol F can be subjected to a condensation process in which a polymeric resin called Novalac is produced. The Novolac can be reacted with epichlorohydrin to produce a polyglcidylether and these are called novolac glycidyl ethers (NOGE).
