Wikipedia Overview
4,4′-Methylenebis(N,N-diglycidylaniline), commonly abbreviated as 4-DGA or TGDDM, is a tetrafunctional aniline-based epoxy resin monomer. It can undergo ring-opening polymerization with various acid anhydride curing agents—such as methyl tetrahydrophthalic anhydride (MTHPA), methylhexahydrophthalic anhydride (MHHPA), maleic anhydride, and glutaric anhydride—to form highly crosslinked thermosetting networks. TGDDM not only contributes rigid aromatic rings that help adjust the glass transition temperature (Tg) of the network but also provides tertiary amine groups that can catalyze the virtrification process and transesterification reactions.
