提出了一种测定透明聚合物片材光学各向异性的新方法，并应用于商品聚丙烯和尼龙6。该方法可以在短至10秒的时间内确定延迟、双折射、取向角和最小与最大光强比。它还揭示了各向异性取决于拉伸比和薄膜的位置，并被认为是实际有用的精度和速度。
A new method for determining the optical anisotropy of transparent polymer sheets is developed and applied to commercial polypropylene and nylon 6. The method allows the retardation, birefringence, orientation angle, and minimum‐to‐maximum light intensity ratio to be determined in as short a time as ∼10 s. It also reveals anisotropy that depends on draw ratio and position of the film, and is considered practically useful for its accuracy and speed.
