摘要： A polarizing film includes a first phase of a first polymer having a birefringence of at least 0.05 and a second phase of a second polymer disposed within the first phase. The index of refraction difference between the first and second phases is greater than about 0.05 along a first axis and is less than about 0.05 along at least one axis orthogonal to the first axis. The diffuse reflectivity of the first and second phases taken together along at least one axis for at least one polarization state of electromagnetic radiation may be at least about 30%. In some exemplary embodiments, the second phase has a refractive index of about 1.53 to about 1.59. In some exemplary embodiments, the second polymer has a glass transition temperature (Tg) higher than the Tg of the birefringent first polymer.

摘要： A method of stretching films in which all or a portion of the width of the film is cooled during or just after stretching so as to improve the uniformity of the film. The includes stretching a polymeric film in a tenter that grasps the film with a plurality of clips along the opposing edges of the film and propels the clips to thereby stretch the film. The tenter includes driven clips and idler clips, with at least one idler clip between respective pairs of driven clips. The cooling is done so as to improve the uniformity of the clip spacing relative to the spacing obtained at otherwise identical process conditions without such cooling.
