An epoxydinaphthalene monomer for the synthesis of a poly(aryl ether sulfone) and a poly(aryl ether ketone) with enhanced performance for membrane gas separations
A novel monomer based on epoxydinaphthalene (EDN), a highly rigid bridged-bicyclic structural unit, was prepared using a high yielding reaction between 2,7-hydroxynaphthalene and the hydrate of 1,8-naphthalene dialdehyde. This monomer was used to make a poly(aryl ether ketone) and poly(aryl ether sulfone), EDN-PAEK and...
