    摘要: The invention relates to thermoplastic molding compounds of 70 to 99.5% by weight thermoplastic polyamides and 30 to 0.5% by weight hydrogenated nitrile rubber and 0 to 29.5% by weight thermoplastic resin components and, optionally, standard additives in typical quantities. These thermoplastic molding compounds show high strength values, very good moldability and, above all, high weathering resistance.
