Beschreibung
Zusammenfassung:	Thermoplastic compositions particularly adapted for use in preparing extruded fibers and films for carpets, rugs, woven fabrics, non-woven or spun-bonded fabrics, knit fabrics, garments, laminates, constructions, or other applications and a method for the formation thereof. An extruded and drawn fiber comprising a thermoplastic polymeric composition comprising: (a) from 76 to 97 percent by weight of a first thermoplastic polymer comprising a polyamide or copolyamide having a crystallization temperature, Tc, greater than 160 DEG C; (b) from 24 to 3 percent by weight of a second thermoplastic polymer comprising a polyvinylidene aromatic polymer having isotactic or syndiotactic stereostructure and a crystallization temperature, Tc', and (c) optionally, a compatibilizer for (a) and (b),wherein said percentages are based on the sum of (a) and (b), and wherein Tc is at least 5 DEG C less than Tc'.
