Beschreibung
Zusammenfassung:	For improved flame retardant finishing and better processability of an epoxy anhydride reaction resin system, the present invention provides a reaction resin system supplemented with phosphinic and/or phosphonic acid anhydride as the hardener component. The phosphorus-containing anhydrides do not deteriorate the hardening characteristics. Molded members manufactured therefrom exhibit adequate flame retardant behavior even with slight proportions of phosphinic or phosphonic acid anhydride given a property profile that is otherwise unmodified.
