Abstract
The application discloses compositions which can be shaped to form yarns, fibers, films, membranes and fibrids. They contain a particular statistical or ordered copolyamide, with an inherent viscosity of at least 1, or units containing radicals of which at least 5% are flexible radicals and the others are rigid radicals. These compositions make it possible to produce yarns, fibers, films, membranes and fibrids possessing superior mechanical properties, which find applications in the textile field, as reinforcements in composite materials in the rubber industry and coated fabrics.
