Abstract
The invention relates to a chemically degradable cured epoxy resin system containing one or more epoxide resins and one or more curing agents, characterized in that the curing agent contains at least one cyanate, with which the epoxy resin reacts to form an epoxy resin polymer containing cyanurates. The cured epoxy resin system can be recycled by chemically decomposing the cured component epoxy resin system by aminolysis with reactive NH— or other amino groups and/or alcoholysis with mono-, di-, or poly functional alcohols.
