Abstract

The invention relates to reaction resins formed from anionically polymerizable di- or tri-functional epoxy compounds which are suitable for impregnating and/or casting large-volume parts. Such reaction resins therefore contain tertiary amine polymerization catalysts of the general formula ##STR1## in a concentration of 0.5 to 10 mass parts, relative to 100 mass parts epoxy compound.
