摘要:
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 (1a) or (1b), 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.

摘要:
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 where R1, R2, R3 R4, R5 and R6 independently denote H, alkyl, aryl, heteroaryl or halogen, or where R1, R2, R3, R4, R5, R6 and R7 mutually independently stand for H, alkyl, aryl, heteroaryl, halogen or a cyano group.
摘要:
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.
摘要:
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.
