    • A process for preparing poly{[benzo (1,2-d:5,4-d')bisthiazole-2,6-diyl]-1,4-phenylene} or one of the reactants used in the preparation of such polymer by the use of an electrolytic cell. In the process, thiocyanate ions are oxidized to thiocyanogen in the anode chamber of the cell. In a preferred embodiment, the cathode chamber of the same electrolytic cell is used to reduce 4,6-dithiocyanobenzene-1,3-diamine to form the dithio radical of 4,6-diaminobenzene-1,3-dithiol. Upon hydrogenation, the dithiol or its acid salt may be used to react with terephthalic acid to form the polymer.
    • 制备聚{[苯并(1,2-d:5,4-d')双噻唑-2,6-二基] -1,4-亚苯基}或用于制备这种聚合物的反应物之一的方法 使用电解池。 在该过程中,硫氰酸根离子在电池的阳极室中被氧化成硫氰化物。 在优选的实施方案中,使用相同电解槽的阴极室来还原4,6-二硫氰基苯-1,3-二胺以形成4,6-二氨基苯-1,3-二硫醇的二硫基。 氢化时,二硫醇或其酸盐可用于与对苯二甲酸反应形成聚合物。

    • Provided is an archival recording medium and a method for recording information on same. The recording medium comprises a microporous polymeric layer and an energy-absorbing material, e.g., a layer of an energy-absorbing material such as a metal or dye/polymer layer deposited on the microporous layer. If desired, further dimensional stability and mechanical strength can be provided by a thermally stable substrate or by tensioning the medium within a rigid frame. Information is recorded by the energy-absorbing material heating up in localized irradiated regions and causing the controlled collapse of the microporous structure in the microporous polymer layer. The collapsed portions of the structure constitute the information which can then be read either by reflectance or transmission.
    • 提供了一种档案记录介质和用于记录信息的方法。 记录介质包括微孔聚合物层和能量吸收材料,例如沉积在微孔层上的诸如金属或染料/聚合物层的能量吸收材料层。 如果需要,可以通过热稳定的基底或通过在刚性框架内张紧介质来提供进一步的尺寸稳定性和机械强度。 通过在局部照射区域中加热的能量吸收材料记录信息,并导致微孔聚合物层中的微孔结构受到控制的崩溃。 结构的折叠部分构成了可以通过反射或透射来读取的信息。
