    • The present invention relates to a thermoformable multilayer film comprising in succession: an optional protective layer (A); a layer (B) comprising (the total being 100% by weight) 0 to 30% of a fluoropolymer (B1) and 100 to 70% of a functionalized polymer (B2) essentially consisting of alkyl (meth)acrylate units; a layer (C) based on an ethylene/alkyl (meth)acrylate/unsaturated epoxide copolymer; a polyolefin tie layer (D); the layers adhering to one another in their respective contact regions. This film is obtained by coextrusion or coating of the various layers, the layer (A) possibly being laminated using the standard technique for thermoplastics. This film is then used to cover various substrates, for example by injecting the substrate in the melt onto the multilayer film deposited in the bottom of an injection mould, the layer (B) or the optional layer (A) of the film being placed against the wall of the mould. The present invention also relates to the substrates coated with these films.
    • 本发明涉及一种可热成型的多层膜,其包括:可选的保护层(A); 含有(总共为100重量%)0〜30%的氟聚合物(B1)和100〜70%的主要由(甲基)丙烯酸烷基酯单元组成的官能化聚合物(B2)的层(B) 基于乙烯/(甲基)丙烯酸烷基酯/不饱和环氧化物共聚物的层(C) 聚烯烃粘结层(D); 这些层在各自的接触区域中彼此附着。 该膜通过共挤出或各层的涂覆获得,层(A)可能使用热塑性塑料的标准技术层压。 然后将该膜用于覆盖各种基材,例如通过将熔体中的基材注入沉积在注射模具底部的多层膜上,将膜(B)或膜的任选层(A)放置成抵抗 模具的墙壁。 本发明还涉及涂覆有这些膜的基材。

    • A polymer composition comprises at least one thermoplastic polymer selected from the group formed by polyetherimides and polysulphones, at least one epoxy resin modified by at least one aromatic polyamine, and at least one other thermoplastic selected from the group consisting of a polyphenylene ether, a polyphenylene sulfide and an aromatic polyether. The epoxy resin is formed from at least one polyepoxide containing at least 2 epoxy groups in its molecule and the aromatic polyamine contains at least two primary amine groups in its molecule and preferably at least one alkyl substituent containing 1 to 12 carbon atoms located alpha to one of the amino groups. The molar ratio of the polyamine to the epoxy is such that, each amino group corresponds to 1.6 to 2.6 epoxy groups. The thermoplastic polymer content is preferably about 15% to 98% by weight with respect to the total weight of the polymer composition; the amount of epoxy resin modified by at least one aromatic polyamine is about 2% to 85% by weight with respect to the total weight of the polymer composition.
