Abstract:

Benzoxazine resins, a new type of thermosetting resin, are featured by strong molecular design ability, flame retardancy, high corrosion resistance, independence on strong acids during thermosetting, and no release of small molecules and thus they are widely used in aviation, architecture, electronics and other fields. In this study, the methods of benzoxazine monomer(solvent method, solvent-free method and suspension method), the synthesis methods to reduce the ring opening polymerization temperature of benzoxazine(synthesis of benzoxazines with special groups and addition of catalysts), and the application of benzoxazine resins into shape memory polymers were introduced(mixed with other polymers and chemical modification of benzoxazine). Moreover, the existing problems concerning benzoxazine shape memory polymers were summarized. Finally, the prospects about the development of benzoxazine resins in shape memory polymers were proposed.

Key words: benzoxazine resins, synthesis, ring-opening polymerization, shape memory
