    摘要: Disclosed herein are backlit devices comprising multiwall sheets (120,220). In one embodiment, a backlit device comprises: a multiwall sheet (120,220) and a light source (106). The multiwall sheet (120,220), that has a viewing side (114), comprises polymer walls and a rib that intersects at least two of the walls. The rib comprises a non-linear geometry. The light source (106) is located on a side of the multiwall sheet (120,220) opposite the viewing side (114), wherein the light source (106) is configured to direct light (104) at the multiwall sheet (120,220).

    摘要: There is provided an optical plate. The optical plate includes a supporting substrate and an optical diffuser film. The optical diffuser film has a density of light scattering particles to provide light diffusion. The optical diffuser film has a surface facing the supporting substrate, wherein a first portion of the surface facing the supporting substrate contacts the supporting substrate. There exists a gap between a second portion of the surface facing the supporting substrate and the supporting substrate, wherein the ratio of the area of the first portion to the second portion is less than 10%.

    摘要: A process that is provided for agglomerating rubber particles of a rubbery latex. The process involves producing an agglomerating agent which is in the form of latex having particles which comprise high molecular weight polyoxyethylene bound therein. The agglomerating agent is affixed with an elastomeric latex to form agglomerated elastomeric particles. The process results in the formation of uniform size agglomerating particles, and utilizes a non-surfactant form of polyoxyethylene, which can be utilized in small amounts to yield the desired agglomerated elastomeric latex. The agglomerated particles may then be utilized as the substrate for graft copolymers, such as acrylonitrile-butadiene-styrene graft copolymers.
