Epoxy resins can be thermally cured with anhydrides to build polymers with sizeable property retention at elevated temperatures for extended amounts of time. Response and subsequent crosslinking manifest only soon after opening with the anhydride ring, e.g. by secondary hydroxyl groups while in the epoxy resin. Homopolymerization may also happen amongst epoxide and hydroxyl teams. The high latency of anhydride hardeners can make them appropriate for processing systems which have to have addition of mineral fillers before curing, e.
