Reaktionsschritte

A reaction vessel was charged with 442 parts Epoxy B, 442 parts Epoxy E, 116.0 parts succinic acid, 110 parts methyl ethyl ketone, and 3 parts tri-n-butylamine (catalyst). The temperature was raised to 150° C., while removing sufficient MEK (100 parts) to maintain controlled reflux at this temperature. The reaction maintained at 150° C., for 1.5 l hours and then poured into a poly(tetrafluoroethylene) lined tray and allowed to cool to ambient temperature. The resulting solid resin had an acid number of 32.0 and an epoxy content of 0.03 meq./g.
