A high impact polyamide composition comprising at least one polyamide, at least one ethylene ionomer resin and at least one oxide or carbonate compound is specific weight proportions, wherein the polyamide has a relative viscosity of at least 3.15 in 98% sulfuric acid. The composition may further comprise an elastomeric olefin copolymer, an elastomeric styrene copolymer and/or a polyvalent alcohol. The polyamide composition has excellent mechanical strength, thermal resistance and impact strength even at weld-line portions so that it can advantageously be employed for manufacturing various shaped articles, such as automobile parts and sporting goods.
