“…[17,18] Our laboratory has been engaged in developing novel polytriazole (PTA) resins with low temperature curing and high heat-resistance ten years ago. [19][20][21][22] Some of the resins could be used as a matrix of high performance composites. The cured PTA resin had good heat resistance and high mechanical properties.…”

A novel series of polytriazole resins were synthesized by using aromatic diazides and N,N,N′,N′-tetrapropargyl-p,p′-diaminodiphenylmethane (TPDDM) as raw materials. The chemical structures of the resins were characterized by Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance. Rheological behavior indicates that the resins can be processed in a low-temperature region, and some of them have good solubilities in common organic solvents. Differential scanning calorimetry and FTIR results demonstrated that the polytriazole resins can be cured at 70°C. The glass transition temperature (T g ) of cured resins increased with the increase in rigidity of diazide units in polymer chains and reaches up to 328°C.

“…[19,20] As shown in Table 4, curing degrees change with the curing temperature and time. The curing degrees based on the peak at 3290 cm À1 correspond with those on the peak at 2110 cm À1 , even though there exists slight difference.…”

“…[19][20][21][22][23][24] A new kind of thermosetting resin with terminal propargyl groups has recently been developed as a high-performance polymer owing to its good processability, advantageous dielectric and mechanical properties and excellent thermal stability, whether in air or in a nitrogen atmosphere. [25][26][27][28][29][30] This paper presents new modified BMI resins prepared from BMI, HSQ and dipropargyl aryl ethers. We investigated the processability, mechanical properties and heat resistance of the resins and their composites.…”

A new type of modified bismaleimide (BMI) resins with good heat resistance and processing properties for advanced composites was developed. Modifiers hydrogen silsesquioxane (HSQ), dipropargyl ethers of bisphenol A, hexafluorobisphenol A, 4,4¢-dihydroxydiphenyl ether and resorcinol were used to modify 4,4¢-bismaleimidodiphenylmethane. The structure of the resins was verified by Fourier transform infrared spectrometry. The relationship between viscosity and temperature was used to characterize the processability of the resins. The curing behaviors of resins were investigated by a differential scanning calorimeter. The glass transition temperatures and thermal stabilities of cured resins were investigated by dynamic mechanical analysis and thermogravimetric analysis, respectively. The relationship between structures and properties of the resins was discussed, and the mechanical properties of the glass-fiber-fabric-reinforced composites were measured.
