1,2,4-triazole-functional PGMA polymers have been synthesized and their anhydrous proton-conducting properties were investigated after doping with phosphoric acid and triflic acid. PGMA was prepared by solution polymerization and then modified with 1H-1,2,4-triazole (Tri) and 3-amino-1,2,4-triazole (ATri). FT-IR, 13C NMR and elemental analysis verify the high immobilization of the triazoles in the polymer chain. Phosphoric-acid-doped polymers showed lower Tg and higher proton conductivities. PGMA-Tri 4 H3PO4 showed a maximum water-free proton conductivity of approximately 10-2 S · cm-1 while that of PGMA-ATri 2 H3PO4 was 10-3 S · cm-1. The structure and dynamics of the polymers were explored by 1H MAS and 13C CP-MAS solid-state NMR.
