Abstract

See full text

Polyhemiaminal (PHA) and polyhexahydrotriazine (PHT) materials are modified by 1,4 conjugate addition chemical reactions to produce a variety of molecular architectures comprising pendant groups and bridging segments. The materials are formed by a method that includes heating a mixture comprising solvent(s), paraformaldehyde, aromatic amine groups, aliphatic amine Michael donors, and Michael acceptors, such as acrylates. The reaction mixtures may be used to prepare polymer pre-impregnated materials and composites containing PHT matrix resin.
