摘要：This article reviews the researches on the relationship between structures and properties of a new kind of polytriazole resins. After introduction to the preparation of the resins, the thermal behaviour and reactivity of crosslinkable polytriazole resins are discussed. The effects of the chains rigidity, polarity of chain units, functionality of monomers, grid size of crosslinked network on glass transition temperatures of the polytriazole resins are described. Furthermore, the effects of structures of the polytriazole resins on the mechanical properties, dielectric properties, thermal stabilities are demonstrated. The researches show that the curing reaction of the resins would take place at about 75°C. The glass transition temperatures of the resins change with the chains rigidity, polarity of chain units, and crosslinking degree. The highest one reaches 324°C. The mechanical properties, dielectric properties, thermal stabilities of polytriazole resins are also influenced to some extent by the structures of the polytriazole resins. The flexural strength of a crosslinkable polytriazole resin, A2B4, arrives at 200 MPa. The polytriazole resins are expected to be used in advanced polymeric composites. ? 2011 Scrivener Publishing LLC. All rights reserved.
