Abstract
Improved thermoplastic compositions adopted for easy conversion, e.g., by injection molding or extrusion techniques, into useful shaped articles having high flexibility, and good tear resistance and elasticity, include a polyetheramide, advantageously a polyetheresteramide, and a styrene/diene copolymer, e.g., a copolymer of styrene with butadiene or isoprene, notably a linear or branched chain styrene/butadiene/styrene or styrene/isoprene/styrene copolymer.
