ABSTRACT:
It has now been found that a unique combination of additives makes semi-crystalline polyamides readily processible by extrusion blowmolding to make hollow, stiff parts of various shapes. The compositions consist essentially of a semicrystalline polyamide, a selected ionomeric toughening agent, and an anhydride-rich ethylene copolymer.
