为了进一步研究聚合离子液体体系中的亚劳斯模式，采用自制的剪切和拉伸流变光学装置研究了两种聚（1-丁基-3-乙烯基咪唑）基聚合离子液体（PC（4）VINfO和PC（4）VICPFSI）的动态粘弹性和双折射率.其抗衡阴离子与TFSI-具有相同的化学结构，但不同形状的PC 4VICPFSI的亚劳斯模式光谱显示出与PC 4VITFSI的亚劳斯模式相同的组分函数。另一方面，其抗衡阴离子与TFSI具有相同的离子尺寸但化学结构不同的PC（4）VINfO的亚劳斯模式光谱变得比PC 4VITFSI的亚劳斯模式光谱更尖锐。这一结果表明，反阴离子的增塑作用将更负责亚劳斯模式。
Dynamic viscoelasticity and birefringence of two poly(1-butyl-3-vinylimidazolium) based polymerized ionic liquids, PC4VICPFSI and PC(4)VINfO, are investigated by using hand-made shear and tensile rheo-optical apparatus for a further consideration of sub-Rouse mode in polymerized ionic liquids systems. Sub-Rouse mode spectrum for PC4VICPFSI whose counter anions is the same chemical structure as TFSI- and different shape showed the same component function as sub-Rouse mode for PC4VITFSI. On the other hand, sub-Rouse mode spectrum for PC(4)VINfO whose counter anions is the same ionic size as TFSI- but different chemical structure became sharper than that of PC4VITFSI. This result indicated that plasticization effect of counter anions would be more responsible for sub-Rouse mode.
