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: A recipient is provided comprising an outer rigid housing and an inner flexible bag under butane gas pressure, in which the inner flexible bag is a material comprising a mixture of polyamide forming a matrix and of functionalized ethylene polymer comprising a functionalized ethylene/(meth)acrylate copolymer.

Abstract: The present invention relates to a film (A) consisting of a mixture comprising at least one polyamide and at least one polyolefin, the said film being placed on agricultural land into which a fumigant is injected. According to a first variant, the invention also relates to a film comprising the above layer (A) and a layer (B) consisting essentially of a polyolefin. According to a second variant, the invention also relates to a film comprising the above layer (A) placed between two layers (B). A coextrusion binder may optionally be placed between the layers (A) and (B) in the two variants. The invention also relates to a process for the treatment of soils by fumigation.
