Copolymers comprising poly(ethylene oxide) and cationic glycidyl triazolyl polymer with tribranched side chains (PEO-co-GTP·3X) were synthesized from glycidyl azide copolymer (PEO-co-GAP) and the tricationic alkyne. A synthetic route for the tricationic alkyne was also improved. Bis(trifluoromethanesulfonyl)imide (TFSI) and bis(fluorosulfonyl)imide (FSI) were used as counteranions. Copolymers PEO-co-GTP·3TFSI and PEO-co-GTP·3FSI were characterized by NMR, IR, size exclusion chromatography, DSC, TGA, rheological, and impedance measurements. The NMR results suggested that the main chain of the copolymer was more flexible than that of the homopolymer. However, no major changes were detected in the glass transition temperature and ionic conductivity of the homopolymer and copolymer with TFSI counteranions. The counterion exchange from TFSI to FSI resulted in an increase in the storage modulus and complex viscosity because of the ionic association. Despite its unfavorable viscoelastic properties, PEO-co-GTP·3FSI exhibited higher ionic conductivity than PEO-co-GTP·3TFSI (3.9 × 10^–5 S cm^–1 at 25 °C under anhydrous conditions).

基于聚（环氧乙烷）和具有三支化侧链的阳离子缩水甘油基三唑基聚合物的共聚物的聚（离子液体）

由缩水甘油基叠氮化物共聚物 (PEO- co - GAP) 和三阳离子炔烃合成包含聚(环氧乙烷) 和具有三支化侧链的阳离子缩水甘油基三唑基聚合物 (PEO- co -GTP·3X) 的共聚物。还改进了三阳离子炔烃的合成路线。双(三氟甲磺酰)亚胺(TFSI)和双(氟磺酰)亚胺(FSI)用作抗衡阴离子。共聚物 PEO- co -GTP·3TFSI 和 PEO- co-GTP·3FSI通过NMR、IR、尺寸排阻色谱、DSC、TGA、流变学和阻抗测量进行了表征。NMR结果表明共聚物的主链比均聚物的主链更柔韧。然而，在具有 TFSI 抗衡阴离子的均聚物和共聚物的玻璃化转变温度和离子电导率方面没有检测到重大变化。由于离子缔合，从 TFSI 到 FSI 的抗衡离子交换导致储能模量和复数粘度增加。尽管具有不利的粘弹性， PEO- co -GTP·3FSI 表现出比 PEO- co -GTP·3TFSI 更高的离子电导率（在 25 °C 无水条件下为3.9 × 10 ^–5 S cm ^{–1 ）。}
