Abstract: The present invention relates to a masterbatch comprising by weight: from 1 to 50% of a blend of at least one fluoropolymer (A) and at least one interfacial agent (B); from 99 to 50% of a polyolefin (C); such that the two constituents (A) and (B) are intimately blended beforehand at a temperature such that at least one is in the melt state throughout its mass or on its surface, and are then blended with the polyolefin (C). The invention also relates to the use of the masterbatch as a processing aid for extruding a polyolefin (D), in particular for extruding a film-form polyolefin. The invention also relates to the process for obtaining the masterbatch.

Abstract: A multiplayer acrylic film is presented having: a layer (A) made from a thermoplastic acrylic composition a layer (B) made from either a composition comprising a methacrylic (co)polymer and an impact modifying compound, or a composition prepared by sequential polymerization in aqueous emulsion of acrylate-based monomer systems, or a composition comprising a block copolymer, and a layer (C) made from a thermoplastic acrylic composition. The film is useful for coating a substrate (thermoplastic resin, thermosetting resin, etc.).

Abstract: Multilayer acrylic film comprising: a layer (A) made from a thermoplastic acrylic composition comprising from 75 to 95% of a metliacrylic (co)polymer containing mostly methyl methacrylate units and from 5 to 25% of an impact modifier a layer (B) made from either a composition comprising a methacrylic (co)polymer and an impact modifying compound, or a composition prepared by sequential polymerization in aqueous emulsion of acrylate-based monomer systems, or a composition comprising, a block copolymer, and a layer (C) made from a thermoplastic acrylic composition comprising from 75 to 95% of a methacrylic (co)polymer containing mostly methyl methacrylate units and from 5 to 25% of an impact modifier. Use of the film for coating a substrate (thermoplastic resin, thermosetting resin, etc.).

Abstract: 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.
