The rapid development of aerospace technology has put demands on the high tough thermosetting resins. Polytriazole (PTA) resins are a kind of high performance thermosetting resins as matrices of structural composites for aerospace parts. It is necessary to develop polytriazole resins with high toughness. In this paper, propargyl-terminated polypropylene glycols (P t PGs) with various molecular weights (P t PG400, P t PG600, P t PG725) were synthesized and characterized. A series of P t PG-toughened polytriazole (PPTA) resins were prepared by the "Click" reaction of P t PG and N,N,N 0 ,N 0 -tetrapropargyl-4,4 0 -diaminodiphenylmethane (TPDDM) with 1,1-bisazidomethyl-4,4 0 -biphenyl (BAMBP). The curing behavior of the PPTA resins and the thermal, mechanical, as well as water absorption of the cured PPTA resins were investigated. The results show that the PPTA resins have excellent processing properties and can be cured and molded at 80 C. The molecular weight and the amount of P t PG have a significant influence on the mechanical properties of PPTA resins. When P t PG600 with the molar ratio of alkyne groups 1.0% is formulated, the impact strength of the cured PPTA-600-1.0 resin reaches 63.6 ± 8.2 kJÁm À2 and K IC 2.57 MPaÁm À1/2 , which are 57.4% and 41.2% higher than those of PTA resin respectively. The glass transition temperature (T g ) and water absorption of the cured PPTA-600-1.0 resin are 223.8 C and 0.22% respectively.

“…Huang group [16][17][18][19][20][21][22][23][24][25] has prepared a series of thermosetting polytriazole resins by 1, 3-dipolar cycloaddition reaction of azides and alkynes since 2002. The study results have shown that the polytriazole resins are cured at low temperature (60~80°C) and the cured resins have good thermal properties and mechanical properties, and the resins have been used as matrices in advanced composites.…”

Three azido-terminated poly(ethylene glycol) macromonomers (ATPEGs) were synthesized from poly(ethylene glycol)s (PEGs) and characterized. The extended polytriazole (EPTA) resins were prepared from the macromonomers, azide and alkyne monomers. Toughening effect of PEGs on polytriazole resins was analyzed by means of mechanical, thermal and electronic microscope characterization. The results show that molecular weight and content of ATPEGs have great influence on the thermal and mechanical properties of cured EPTA resins. The impact strength of cured EPTA resins increases with the increase of the amount and molecular weight of ATPEGs. The flexural strength and heat resistance of cured EPTA resins decrease with the increase of addition amount and molecular weight of ATPEGs. High impact EPTA resins were obtained.
