  • Publication number: 20150086799
    Abstract: An organic polymer solution may include about 0.1%-30% by weight of a specific polymer having rigid rod-like molecules. These molecules may include various cores, spacers, and sides groups to ensure their solubility, viscosity, and cross-linking ability. The rigid rod-like molecules are selected in such a way that they form self-assembling structures in the polymer solution, which makes it a lyotropic liquid crystal. The organic polymer solution, when properly deposited on a substrate and dried to remove solvents, forms a solid optical retardation layer of positive A-type substantially transparent to electromagnetic radiation in the visible spectral range.

  • Patent number: 7341707
    Abstract: The invention concerns a method for production of microporous crystalline metalloaluminium phosphates (ELAPO) based adsorbents or catalysts by in-situ crystallisation of ELAPO inside a formed body. First the formed body containing aluminium phosphate (AIPO) and binder is prepared, thereafter the organic structure directing agent, EL source and water are added and finally ELAPO is crystallised in-situ at elevated temperature and pressure, while keeping the shape and size of the formed body.
