摘要： A process for producing a UV-stable laminated structure having thermal aging resistance includes coextruding the following layers in a single-stage operation, or laminating the following layers onto one another in a heatable roll nip: a substrate layer made up of a graft copolymer and a styrene and/or (meth)acrylate/(meth)acrylonitrile copolymer, and optionally containing a polycarbonate and a fibrous and/or particulate filler; and a transparent top layer of polymethyl methacrylate. In another embodiment, an interlayer of e.g., impact-modified polymethyl methacrylate or polycarbonate, is coextruded or laminated between the transparent top layer and the substrate layer to produce a UV-stable laminated structure. An adhesion layer containing an adhesion promoter can be coextruded or laminated on the outer surface of the substrate layer. A molding is produced by thermoforming the UV-stable laminated structure, which is advantageously backsprayed or back-cast with the substrate layer or a polyurethane foam. The molding can take the form of an automotive exterior bodywork component.

摘要： Molding materials containing styrene-acrylonitrile copolymers, in which an additional essential ingredient is from 0.1 to 2.0% by weight, based on the copolymer, of a three-block polymer X-Y-X, where X is a terminal ethylene oxide block and Y is a central propylene oxide block. The proportion of terminal ethylene oxide blocks X, based on block copolymer, is from 5 to 20% by weight, while the central propylene oxide block Y has a number-average mean molecular weight of from 700 to 3,000 and its proportion is from 80 to 95% by weight, based on block copolymer. The number-average molecular weight of the sum of the two terminal blocks X is from 140 to 1,000.The novel molding materials may be used for the manufacture of moldings, since the three-block copolymer X-Y-X advantageously influences the processing characteristics of styrene-acrylonitrile copolymers, and in particular broadens the range of conditions under which they may be injection-molded, without adversely affecting the mechanical properties of the styrene-acrylonitrile copolymers. Accordingly, the injection molding scrap rate can be kept very low.
