A multi-layer article is disclosed. The article contains a base layer that contains at least one thermoplastic resin and a second layer containing a thermoplastic (co)polyformal superimposed over the base layer. The (co)polyformal conforms to formulae (1) or (1), in which O-D-O and O-E-O independently denote a diphenolate group, -D- and -E- independently denote an aromatic group having 6 to 40 carbon atoms, k is a whole number from 1 to 1500, o stands for numbers from 1 to 1500, and m is z/o and n is (o-z)/o wherein z is 0 to o.

Polyformals as a coextrusion protective layer on polycarbonate

The present invention relates to a solid sheet prepared from a composition that includes: (a) a transparent polycarbonate; and (b) transparent polymeric particles having an optical density which differs from the transparent polycarbonate matrix material. The present invention also relates to use of such a solid sheet as a diffuser sheet in flat screens.

Light-scattering shaped articles of high light transmission and the use thereof in flat screens

A thermoplastic molding composition characterized by its optical brightness and good weathering resistance is disclosed. The composition contains a poly(ester) carbonate an optical brightener conforming to  

Polycarbonate or polyester carbonate containing optical brighteners

A process for the preparation of a plastic composite is disclosed. The composite contains a first fluoropolymer layer, a second, middle layer of polycarbonate and a third layer of ethylene-vinyl acetate copolymer. The process entails preparing a plastics composite of fluoropolymer and polycarbonate layers and applying the layer of ethylene-vinyl acetate copolymer to the polycarbonate layer.

Multilayer plastic composites and a method for the production thereof

The present invention provides a two-stage process for the production of polyester carbonates with aliphatic dicarboxylic acids, the polyester carbonates obtained thereby, a process for the production of extrudates and molded articles from the polyester carbonates, and the extrudates and molded articles obtained thereby.
