    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.

  • Publication number: 20110233453
    Abstract: It is intended to provide an aqueous solution of a thermoresponsive polymer, which shows an upper critical solution temperature (UCST) and is capable of maintaining a dissolved state, even if it is stored for a long period of time at a temperature at which a ligand such as an antibody or an antigen is not inactivated. A UCST lowering agent is incorporated in a predetermined amount in an aqueous solution of a thermoresponsive polymer which shows a UCST in a state of containing water, thereby lowering the UCST of the aqueous solution to less than the storage temperature, and the resulting aqueous solution is stored.

  • Patent number: 7993749
    Abstract: Acid-labile poly(N-vinyl formamide) (“PNVF”) nanocapsules were synthesized by free radical polymerization of N-vinyl formamide with optional active ingredients on the surface of silica nanoparticles. Polymerization in the presence of a novel cross-linker that contains an acid-labile ketal facilitated stable etching of silica nanoparticle templates using sodium hydroxide and recovery of PNVF nanocapsules. The formamido side group of PNVF was then hydrolyzed by extended exposure to sodium hydroxide to produce polyvinylamine (“PVAm”) nanocapsules. PNVF and PVAm nanoparticles are also synthesized that form nanogels with optional active ingredients.
