Vegetable Oil Derived Solvent, and Catalyst Free “Click Chemistry” Thermoplastic Polytriazoles

Figure 2

(a) ATR-FTIR of the azide monomer (characteristic peak i, 2091 cm⁻¹), alkyne monomer (characteristic peaks ii, 3290 and iii, 2128 cm⁻¹) and polymer C18C9 showing formation of a triazole (characteristic peak iv, 3144.5 cm⁻¹). (b) FTIR spectra of the C18C4, C18C9, and C18C18 polymers. Arrow points to the triazole self-association absorption peak at 1222 cm⁻¹. Insert is a higher resolution zoom into the carbonyl region.
