Abstract: 4-component thermoplastic molding compositions which are easily processed on injection molding or extrusion machinery consisting essentially of amorphous copolyamides which can be produced from inexpensive raw materials, inexpensive elastomeric block polyetherpolyamides and block polyetheresterpolyamides as well as commercially available modified copolyolefins and are distinguished by high cold impact resistance, good ductility, variably adjustable rigidity which is independent of the degree of humidity and excellent pigment compatibility as well as by good stress crack resistance, thermal and dimensional stability.
