摘要： A polymer-dispersed liquid crystal device comprises a multiplicity of droplets of a birefringent, functionally nematic liquid crystal material dispersed in a matrix comprising the reaction product of ultraviolet radiation polymerizable materials. The device specularly transmits incident light as a function of the magnitude of an electric field applied across the device. The difference between a first applied voltage corresponding to a first percentage of the total incident light transmitted by the device as a specular light and a second applied voltage corresponding to a second percentage of the total incident light transmitted by the device as specular light is greater than or equal to 15 volts. As a result, a polymer-dispersed liquid crystal device according to the invention displays a variable grey scale which has a uniform optical transmission. A method for preparing a PDLC device in general is also disclosed.

摘要： A method of preparing a laminate that includes the steps of (a) introducing a first substrate (26) having first and second surfaces and supported at two or more points into a lamination zone (L) located between two of the support points (the first substrate being unsupported throughout the lamination zone); and (b) introducing a second substrate (12) having first and second surfaces into the lamination zone (the second substrate passing around a lamination bar (30) to position the first surfaces of the substrates in a facing relationship with each other). At least one of the first surfaces is provided with coating which is most preferably a solvent-free polymerization coating. Next, in step (c), the lamination bar (30) is depressed to laminate the second substrate to the first substrate.

摘要： A method of coating the surface of a substrate with an essentially solvent-free polymerizable fluid that includes passing the fluid through a die onto the surface of the substrate as the substrate moves relative to the die. The die includes a channel adapted to receive the fluid and an adjustable width slot in communication with said channel through which the fluid is passed formed between a substantially straight, sharp edge located on the downstream side of the substrate and a land located on the upstream side of the substrate.

摘要： Disclosed is a novel, multi-stage irradiation process for the production of acrylic-based compositions such as adhesives or pressure-sensitive adhesive tapes. The first irradiation step or stage employs electromagnetic radiation at a relatively low average intensity (i.e., 0.1 to 20 mW/cm2) to effect a relatively low extent of monomer conversion, and the subsequent step employs electromagnetic radiation at a relatively higher average intensity (i.e., greater than 20 mW/cm ) to complete the photopolymerization. Also disclosed are acrylic-based psa tape materials made by the novel process.

摘要： Glass microbubbles having an inorganic thin-film coating not exceeding about 10 nm in thickness, especially a coating of a metal, a metalloid, or a alloy thereof. When dispersed throughout a matrix such as a polymer, the coated glass microbubbles can afford surprisingly good hiding power while also imparting esthetically pleasing colors to otherwise transparent articles.
