Thermoplastic molding material comprises 50-99 wt.% of a polyamide, 0.01-10 wt.% of a crosslinking agent and 0.1-30 wt.% of an impact modifier. Independent claims are also included for: (1) producing monofilaments by converting the molding material into granules, drying the granules at 80[deg] C for at least 6 weeks until the moisture content is 0.04% or less, melting the granules in a single-screw extruder and spinning the melt; (2) monofilaments produced as above. Die vorliegende Erfindung betrifft thermoplastische Formmassen auf Basis von Polyamiden mit viskositätserhöhenden Zusätzen, daraus hergestellte Extrudate sowie Monofilamente und deren Verwendungen als Schnüre, Seile oder Taue, bevorzugt als Trimmerschnüre oder Mähfäden.
