    摘要: A display having (a) a first electrode; (b) a second electrode; (c) a display medium positioned between the first and second electrodes, which display medium is switchable between a first state in which incident light is at least one of scattered and absorbed and a second state in which the amount of such scattering and/or absorption is reduced; and (d) scattering centers disposed in front of the second electrode for scattering incident light with a scattering half angle of between about 2 and about 40 degrees when the display medium is in its second state, while permitting at least 10% of the incident light to be transmitted.

    摘要: A conductive polymer composition which has a resistivity at 20.degree. C. of at most 1.0 ohm-cm and a PTC anomaly of at least 10.sup.4 contains at most 64% by volume of a crystalline polymeric component and at least 36% by volume of a particulate conductive filler. A preferred conductive filler is carbon black having a DBP number of 60 to 120 cm.sup.3 /100 g. Compositions of the invention, as well as other conductive polymer compositions are preferably prepared by a method in which the polymeric component and the filler are blended in a first step at a temperature greater than the melting temperature of the polymer, the mixture is then cooled, and the mixture is then mixed in a second step. The resulting composition has a PTC anomaly that is at least 1.2 times the PTC anomaly of the first mixture.
