Polyhemiaminal And Polyhexahydrotriazine Materials From 1,4 Conjugate Addition Reactions |
摘要 |
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. |

a plurality of trivalent hexahydrotriazine groups having the structureand
a plurality of phenyl groups having the structure wherein each wavy bond site of a given hexahydrotriazine group is covalently linked at a respective wavy bond site of a phenyl group, and each wavy bond site of a given phenyl group is covalently linked at a respective wavy bond site of a hexahydrotriazine group, and wherein at least one of A, B, C, D, and E is a chemical group that is a reaction product of a 1,4 conjugate addition chemical reaction. |
