“…The value of T g ∞ was a little larger than the measured value 94 by Dynamic Mechanical Analysis of the linear polytriazole 13. The reasons were that: (1) the measured linear PTA was with a limited molecular weight; (2) DMA was usually carried out under a much lower heating rate than DSC.…”

Crosslinked structures of a resin had a great influence on its properties. Studying the effect of a crosslinked network on resin properties will benefit to design and prepare a new resin with good performances. A series of alkyne group-capped oligomers were designed and well characterized. The corresponding crosslinked polytriazoles with different network grids were obtained when multifunctional azide monomer was used as a crosslinking agent. The glass transition temperature (T g ) of the crosslinked polytriazoles was measured by Differential Scanning Calorimetry. The results showed networks with a small grid size would exihibit high T g s. The relationship between T g and the size of the network grids of the crosslinked polytriazoles was discussed.

“…Polytriazole resin has been used in high‐temperature applications owing to their excellent thermal stability and resistance to thermal oxidative degradation . Although the thermal conductivity of pure polytriazole resin is only 0.2W/m·K, the thermal conductivity of polytriazole‐based fiber reinforced composites is about 0.6W/m·K, which is nearly two times than that of polytriazole resin, and it shows that it is difficult to meet the requirement of super insulation materials in the industrial application.…”

To decrease the thermal conductivity of polytriazole‐based fiber reinforced composites, an organic–inorganic POSS/polytriazole hybrid resin was obtained. The influences of various proportions of POSS on thermal conductivity and the thermal properties of hybrid materials were emphatically investigated. The results show that POSS incorporation resulted in not only decreased thermal conductivity but also increased Tg and thermal decomposition temperature. The enhancement was ascribed to the nanoscale effect of POSS structure and the fact that the POSS framework has a high heat resistance property. © 2015 Wiley Periodicals, Inc. J. Appl. Polym.

“…[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] The classical (thermal) 1,3-dipolar cycloaddition can be performed between azides and terminal alkynes as well as internal triple bonds. Generally, the reactivity of alkynes for the click reaction is rather low due to its high electron density at the alkyne functionality.…”

The synthesis of three different electron-defi cient internal alkynes for the metal-free 1,3-dipolar azide-alkyne cycloaddition is shown. The alkynes are polymerized with several multifunctional azides and the reaction enthalpy (Δ H ) is investigated by differential scanning calorimetry (DSC). The mechanical properties of the resulting polymers are analyzed using nanoindentation. The polymerization results in hard materials with an E -modulus of maximum 2.5 GPa, which make them interesting in particular for biomedical applications.
