Abstract: The present disclosure relates to a heat-ageing resistant polyamide molding compound, a molded object made from said polyamide molding compound, and the use of said molded object.

Abstract: Described herein is a polyamide composition [composition (C)] including: from 0 to 30% wt of at least one polyamide [polyamide (A)]; and from above 30 to 99.99% wt of at least one branched polyamide different from polyamide (A).

Abstract: The present disclosure relates to a heat-ageing resistant polyamide molding compound, a molded object made from said polyamide molding compound, and the use of said molded object.

Abstract: The present invention relates to the use, as water vapour barrier, of a film, of a textile or of a layer of material P, said material P comprising, or even consisting of, at least one copolymer A which is a polyamide of PAXY/XAIS Mn+1/n type or of PAZ/XAISMn+1/n type. It also relates to a construction element comprising a film, a textile or a layer of said material P and a construction material.

Abstract: The use of a polyamide modified by sulfonate functions which has improved barrier properties is described. Further described is the use of a sulfonate, aliphatic or aromatic compound for manufacturing a modified polyamide having improved fluid-barrier properties. The composition as described includes a modified polyamide, which is optionally a composition in the form of granules or powder used in manufacturing articles by an injection or extrusion blow-molding method.

Abstract: The invention relates to a method for the melted production, especially by reactive extrusion, of block copolyamide comprising at least one aliphatic polyamide block and at least one semi-aromatic block, especially wherein the aromatic group has at least one hydroxyl or sulfonate function. The invention also relates to the block copolyamide that can be produced by said method; to a composition comprising the block copolyamide; to granules comprising such a copolyamide or such a composition; to a method for producing an item from a copolyamide or a composition of said copolyamide; and to uses of the copolyamide.
