Seven polyimides were synthesized and their films were uniaxially stretched to observe the variation in their in-plane birefringence. The creep method of DMA was used instead in stretching the PI films. The preload force and isothermal temperature were the two controlled factors that were chosen on the basis of the lowest stretchable force and lowest temperature for each PI structure. The elongation ratio of a PI film was then decided by the stretching time.

在此是以DMA 的另一种试片拉伸方式-Creep模式，来取代之前的Stress Relaxation模式对PI薄膜试片进行拉伸实验，Creep模式是以最低的拉伸力量及最低的拉伸温度的前提下，选择Pre-load Force与Isothermal Temperature这二项为拉伸控制因素，在此状态下的PI薄膜拉伸比是取决於其拉伸的时间，此种拉伸模式将可得到较高的拉伸比，而高的拉伸比是获取较高薄膜双折射率的必要条件。
