  A polycarbonate polymer or copolymer is synthesised from a dihydroxydiarylalkane which can be halo-substituted; the highly transparent polymer can be mixed with up to 50 wt% of a polystyrene and is molded into a film or sheet, e.g. by extrusion, and uniaxially stretched, preferably by tentering so as not to cause a neck-in ratio or more than 10%. The stretched film has its optical phase retardation controlled to cause (a) a retardation of phase difference of ½ an average wavelength of natural light of wavelength 550 nm with its retardation value controlled to 200-350 nm, preferably 250-300 nm, (b) full retardation of the actual wavelength with its retardation at 475-625, preferably 525-575 nm or (c) an intermediate retardation value of 350-475 nm. The film also has a color difference or lack of unevenness of not more than 20 determined with a spectro­photometer on usually 10 at random locations of the sample film whilst illuminated through crossed Nicol prisms with the film set so that its main optical axis is at 45° to the Nicols. The retardent films are useful in optical filters and liquid crystal displays.

  聚碳酸酯聚合物或共聚物是由二羟基二烷合成的，二羟基二烷可以是卤代的，这种高 透明聚合物可以与最多 50 wt%的聚苯乙烯混合，然后模塑成薄膜或片材，例如通过挤 压，然后进行单轴拉伸，最好是通过拉伸，以免造成缩颈率超过 10%。 拉伸薄膜的光学相位延迟控制为：(a) 相位差的延迟为波长 550 nm 的自然光平均波长的 1/2，延迟值控制在 200-350 nm，最好是 250-300 nm；(b) 实际波长的完全延迟，延迟值为 475-625，最好是 525-575 nm；或 (c) 350-475 nm 的中间延迟值。薄膜的色差或不均匀度也不超过 20，用分光光度计测定，通常是在样品薄膜的 10 个随机位置，通过交叉的尼科尔棱镜照射，薄膜的主光轴与尼科尔棱镜成 45°。 这种阻燃薄膜可用于光学滤光片和液晶显示器。
