  • Patent number: 6896905
    Abstract: A method of forming, by polymerization in an aqueous dispersion at pressures in excess of one atmosphere, a plurality of porous particles having at least one polymeric phase and at least one pore filling phase, wherein the pore filling phase includes a pore filler and a fugitive substance, is disclosed. Replacement of the fugitive substance with a replacement gas is further disclosed. Porous particles having a polymeric phase and pores containing a pore filler, and, optionally, a gaseous phase are also disclosed, as are their aqueous dispersions.

  • Patent number: 6271898
    Abstract: Disclosed are uniformly sized domains of liquid crystals, a method for forming the domains, and their performance in polymer dispersed liquid crystal displays. The method provides the ability to form discrete domains of liquid crystal surrounded by a polymer shell, also known as polymer encased liquid crystals, or PELCs. Further, the method provides for the ability to make PELCs that have uniformly sized particles. Displays made comprising uniformly sized PELCs demonstrate markedly improved electro-optical performance over displays made by conventional polymer dispersed liquid crystal processes.
