    摘要: A liquid crystal display panel comprising structural elements such as transparent conductive films, polarizers, optical retardation films, color filters, light guide plates, light diffusing films, and converging films is disclosed. At least one of the structural elements comprises a layer made from a specific polymer having a saturated water absorption of 0.1-1% by weight at 23.degree. C. and obtained by the ring-opening polymerization of a specific norbornene derivative with a polar group in the norbornene structure. The liquid crystal display panel is light and convenient to use, excellent in the distinctness of image and productivity, and exhibits no deterioration in image quality during the use in severe, high temperature and high humidity conditions for a long period of time.

    摘要: Organic resins with high surface areas and porosities, which are insoluble in organic solvents and contain few or no flexible groups in the resin structure, are disclosed. Also disclosed is a process for making such resins from polyfunctional aryl alkali metal compounds and a second polyfunctional monomer. Such resins are useful as absorbants.
