    • Exemplary methods include includes providing a film comprising at least one polymeric material; widening the film under a first set of processing conditions in a first draw step along the crossweb direction such that in-plane birefringence, if any, created in the film is low; and drawing the film in a second draw step along a downweb direction under a second set of processing conditions, wherein the second set of processing conditions creates in-plane birefringence in at least one polymeric material. Exemplary roll of film includes an oriented optical film characterized by an effective orientation axis. The oriented optical film comprises only one birefringent polymeric material, at least one birefringent material and at least one isotropic material, or a first birefringent material and a second birefringent material, the birefringent materials characterized by effective orientation axes along the MD. The optical film has a width of greater than 0.3 m and a length a length greater than 10 m.

    • Direct lit backlights and associated methods are disclosed in which typically an array of light sources is disposed between a back reflector and a front reflective polarizer. Source polarizers are provided to cover the light sources. Light that passes through the source polarizer towards the front reflective polarizer is partially transmitted and partially reflected by the front reflective polarizer. The partial transmission and reflection can be balanced to enhance illumination uniformity over the output face of the backlight. Direct lit backlights having arrays of polarized light sources are also disclosed, including backlights in which the light sources use LED light sources, and backlights in which the polarized light sources are substantially aligned with each other.
    • 公开了直接点亮的背光灯和相关方法,其中通常将光源阵列设置在后反射器和前反射偏振器之间。 源偏振器被提供以覆盖光源。 通过源极偏振器朝向前反射偏振器的光部分透射并部分地被前反射型偏振器反射。 可以平衡部分透射和反射以增强背光源的输出面上的照明均匀性。 还公开了具有偏振光源阵列的直接点亮的背光源,包括其中光源使用LED光源的背光以及其中偏振光源基本上彼此对准的背光。

    • A refrigerator interior liner can be made of a composition including a monovinylaromatic polymer matrix having an average molecular weight in weight Mw above 150,000 g/mol; rubber particles; and low- Mw plasticizers. The rubber particles can have an RPS volume of about 8.5 μm, a monomodal distribution, a swell index above 13.8, and an RPVF of at least 39%. The composition can be prepared by forming a polymerizable mixture including a monovinylaromatic monomer, and dissolving a viscous rubber in the polymerizable mixture. A free radical initiator and a chain transfer agent can be contacted with the polymerizable mixture at conditions whereby phase inversion subsequently occurs. The chain transfer agent can produce an increase of the rubber to PS phase viscosity ratio within the inversion reactor. Polymerization can be continued until a monovinylaromatic polymer matrix having rubber particles dispersed therein is obtained.
    • 冰箱内衬可以由包含平均分子量Mw大于150,000g / mol的单乙烯基芳族聚合物基质的组合物制成; 橡胶颗粒; 和低Mw增塑剂。 橡胶颗粒可以具有约8.5μm的RPS体积,单峰分布,高于13.8的溶胀指数和至少39%的RPVF。 可以通过形成包含单乙烯基芳族单体的可聚合混合物,并将粘性橡胶溶解在可聚合混合物中来制备组合物。 在随后发生相转化的条件下,可以使自由基引发剂和链转移剂与可聚合混合物接触。 链转移剂可以在反应器内产生橡胶与PS相粘度比的增加。 可以继续聚合,直到获得具有分散有橡胶颗粒的单乙烯基芳族聚合物基质。
