    摘要: An alignment layer for a liquid crystal display device is described. The alignment layer comprises a copolymer of a thermoset polymer containing perfluorinated cyclobutane rings and a thermoplastic polymer containing perfluorinated cylcobutane rings, or a blend of thermoset and thermoplastic homopolymers or copolymers containing perfluorinated cyclobutane rings.This copolymer or blend provides an alignment layer with a cure temperature of less than 250.degree. C., a low dielectric, and a low moisture content. The resultant alignment layer can also provide surface tilt angles suitable for supertwisted nematic-liquid crystal displays.

    摘要: An optical memory storage media is described, e.g. a compact disc. A method of preparing the media (e.g. discs) is also taught. The storage media is formed from a substrate material having tightly bonded to the surface a highly reflective soft metal alloy formed of, for example, an alloy including at least five percent by weight of each of at least two metals selected from the group consisting of cadmium, indium, tin, antimony, lead, bismuth, magnesium, copper, aluminum, zinc and silver.

    摘要: The invention is a selective process for preparing 1,1,1-trichloroethane comprising irradiating a vaporous mixture comprising 1,1-dichloroethane, chlorine and an effective amount of a photocatalyst wherein the photocatalyst is bromine, a compound which liberates bromine in the presence of chlorine, carbon monoxide, nitric oxide or oxygen, with radiation capable of inducing the selective formation of 1,1,1-trichloroethane. Radiation in the wavelength of between about 250 and 550 nanometers is capable of inducing the selective formation of 1,1,1-trichloroethane.
