Abstract: A composition contains at least a copolyamide (PA-1) as a component (I), produced by polymerization of at least one lactam and of a monomer mixture (M) which contains at least a C32-C40 dimer acid and at least a C4-C12 diamine; and a flame retardant (F1) as a component (II). The flame retardant (F1) is selected from melamine cyanurates, magnesium hydroxide, and phosphorus-containing flame retardants. A process can be used for preparing such compositions, and the composition can be used for producing shaped articles.

Abstract: A composition contains at least a thermoplastic polyurethane (TPU-1) and a copolyamide (PA-1), prepared by polymerization of at least one lactam and of a monomer mixture (M). The monomer mixture (M) contains at least a C32-C40 dimer acid as a component (B1), and at least a C4-C12 diamine as a component (B2). A process can be used for preparing such compositions, and the composition can be used for producing shaped articles.
