Abstract: Provided is a composition including (A) 65% to 95% of a polyamide mixture, (B) 7% to 30% of at least one impact modifier or of at least one core-shell entity or of a mixture thereof, and (C) 0 to 5% of at least one additive chosen from stabilizers, dyes, plasticizers, fibers, fillers, processing aids or a mixture thereof. The composition may be used, for example, to produce an article by extruding, injection molding, molding or thermoforming.

Abstract: A transparent molding composition, including by weight: (a) from 30 to 90% of at least one (co)polyamide of formula PACMY/Z, (b) from 10 to 70% by weight of at least one semi-crystalline copolyamide of formula A/WS, (c) from 0 to 10% of at least one impact modifier chosen from the polyether block amides (PEBA) and the core-shell polymers, (d) from 0 to 2% by weight of at least one additive, (e) from 0 to 5% by weight of a prepolymer; the sum of the proportions of each constituent of said composition being equal to 100%, the composition having good alcohol resistance as determined by an ethanol resistance test.

Abstract: The present invention relates to a composition for blow-molding or extrusion, in particular blow-molding, comprising by weight: a) from 88 to 99.95%, more particularly from 89 to 99.9%, in particular from 93 to 99.9%, of at least one semicrystalline aliphatic polyamide having a carbon number per nitrogen atom of greater than or equal to 7, more particularly greater than or equal to 8, b) from 0.05% to 10%, more particularly from 0.1% to 9%, in particular from 0.1% to 5% by weight of at least one branching agent chosen from polyepoxides, polyanhydrides and polyisocyanates, more particularly polymaleic anhydrides and polyepoxides, c) from 0 to 2% of at least one additive, more particularly 10 from 0.1 to 2%, the composition having, after compounding, a melt viscosity of from 10 000 to 300 000 Pa·s, preferably from 15 000 to 220 000 Pa·s, as measured in plane-plane geometry according to ISO standard 6721-10:2015 at a temperature of 250° C., a frequency of 0.292 rad/s and a deformation of 2%, the sum of the constituents a)+b)+c) making 100% by weight.
