Study on Synthesis of PAEKs Containing Triazole Units through Click Reaction and Their Properties

Abstract

A series of novel linear aromatic ether ketone polymers containing triazole units were synthesized by click chemistry and their structures and properties were characterized by FT-IR, 1 H NMR, GPC, TGA, DSC and WAXD. The results showed that these polymers exhibited relatively small molecular weights distributions, good thermal stability and solvent-repelling which could have potential applications as engineering thermoplastic.

Synthesis of Polyethers Containing Triazole Units in the Backbone by Click Chemistry in a Tricomponent Reaction

“…These data indicate that direct polymerization between dibromide with bisethynyl compounds 1a-d in the presence of sodium azide via the click reaction was successful. In comparison with previous works for synthesis of these types of polymers [25], our method is novel, convenient, and in best agreement with click chemistry requirements (benign solvents, room temperature, simple isolation,. .…”
