Abstract: The invention concerns a material based on halogenated thermoplastic resin, comprising long fibers, characterized in that at least one long fiber is in close contact with a polymer based on alkyl (meth)acrylate. The invention also concerns the methods for making such a material and its uses.

Abstract: The invention relates to a coextrusion binder obtained by grafting a mixture of a copolymer of ethylene and of an elastomer of EPR type with an unsaturated carboxylic acid anhydride or its derivatives. The grafted mixture is optionally diluted in another copolymer of ethylene. The binder is useful in preparing polyolefin/binder/polyamide or EVOH structures.

Abstract: The present invention relates to a metal surface coated with a thermoplastic polymer, the coating exhibiting a peel strength at 130° C. (according to DIN 30 670) which is higher than 400 N/5 cm. This value can be obtained by placing between the metal and the thermoplastic a layer of epoxy resin of Tg higher than 120° C. against the metal and then a layer of polypropylene-based binder. The invention is particularly useful for coating the external surface of pipes.

Abstract: There is provided a mixture comprising: (i) a matrix A comprising a polyolefin (A1) and/or a functionalized polyolefin (A2); and (ii) a dispersed phase comprising an alloy B of polyamide (B1) having a polyamide matrix, comprising for example a polyamide (B1), a functionalized polyolefin (B2) and optionally a polyolefin (B3). A method for producing same is disclosed and comprises mixing the constituents of matrix A and a ground product of a multi-layer film comprising at least one layer of alloy B.

Abstract: The invention relates to a coextrusion binder obtained by grafting a mixture of a copolymer of ethylene and of an elastomer of EPR type with an unsaturated carboxylic acid anhydride or its derivatives. The grafted mixture is optionally diluted in another copolymer of ethylene. The binder is useful in preparing polyolefin/binder/polyamide or EVOH structures. These structures are useful in preparing rigid hollow bodies.

Abstract: The invention provides a film having low permeability to hydrocarbons comprising at least one layer (i) formed of a polyamide/polyolefin alloy having a polyamide matrix and at least one layer (ii) formed of a polyolefin. The invention also provides a release film for a sheet molding compound consisting of said film, as well as a packaging for expandable polystyrene formed of said film.

Abstract: The present invention provides a sheet molding compound consisting in a sandwich structure comprising a central layer of reinforced uncured heat hardenable sheet molding compound; and two outer layers of a release film having low permeability to hydrocarbons comprising at least one layer (i) of a polyamide/polyolefin alloy having a polyamide matrix and at least one layer (ii) of a polyolefin.

Abstract: The present invention relates to a modifier composition, a stock mixture and a final composition comprising a fluoro elastomer and a thermoplastic polyamide, as well as to the film obtained from the final composition.

Abstract: The invention provides a coating for a metal surface comprising (i) a primer able to gel and set, (ii) an adhesive and (iii) a thermoplastic polymer, in which said adhesive contains a catalyst, as well as metal objects, particularly pipes, provided with this surface coating, and a method for applying the surface coating.

Abstract: Stampable reinforced thermoplastic sheet, at least one face of which comprises, from the outside to the inside, at least three successive layers abc, in which:a is a matrix comprising a thermoplastic resin reinforced by at least two fillers of different nature and/or type chosen from fillers of the lamellar type and of the spherical or substantially spherical type,b is an interfacial binder chemically compatible with the thermoplastic resin of a and having, with respect to the latter, a lower viscosity at the temperatures at which the sheets are produced and used, andc is a reinforcement comprising a needled glass mat.Articles obtained from the sheets by stamping.
