the backbone of poly(alkoxy- and aryloxyphosphazenes) with strong alkylation reagents. As models for the synthesis of these polymers, similar quaternization reactions were also carried out on small-molecule alkoxy and aryloxy cyclotriphosphazenes. The quaternized small molecules and high polymers were characterized by 1H NMR, 31P NMR, DSC, TGA, and AC impedance studies. The quaternized poly(alkoxyphosphazenes)
通过用强烷基化试剂对聚(烷氧基-和芳氧基磷腈)的主链进行季铵化反应,合成了新型的聚电解质。作为合成这些聚合物的模型,还对小分子烷氧基和芳氧基环三磷腈进行了类似的季铵化反应。季铵化的小分子和高分子聚合物通过1 H NMR,31 P NMR,DSC,TGA和AC阻抗研究进行了表征。季铵化的聚(烷氧基磷腈)在25°C下的离子电导率为2.58×10 –4 S·cm –1,在80°C下的电导率为2.09×10 –3 S·cm –1,是已知溶剂的最高电导率。游离离子导电聚合物。
