摘要:
Methods for preparing uniformly sized polymer particles comprised of multi-functional monomers such as poly(1,4-butanediol diacrylate) and poly(1,6-hexanediol diacrylate) are disclosed. The particles are of a size, uniformity, and contain physical characteristics that make them ideally suitable for use as spacers in liquid crystal display devices.
摘要:
There is provided a polymeric film comprising one or more thermoplastic polyurethane and one or more acrylic polymer comprising, as polymerized units, one or more hydrogen-bondable monomer.
摘要:
Light-scattering compositions comprising diffuser polymer particles are disclosed. Also disclosed are methods of making and using the light-scattering compositions.
摘要:
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.
摘要:
Polymer particles in a size range between 2 and 15 micrometers, and having a refractive index close to, but not identical with, that of a matrix polymer and optionally having one or more enclosing shells, the outer shell being compatible with the matrix polymer, impart light-diffusing properties to the matrix polymer without degrading its physical properties, while the particles having a closer refractive index match to the matrix polymer impart gloss reduction to the surface of the matrix polymer.
