Abstract:
1. Method for the manufacturing of a container or parts of a container for volatile organic compounds (VOC) or compressed gases by extrusion blow molding a molding composition comprising: a) at least one polyoxymethylene (A) having terminal groups comprised of hydroxyl groups, b) at least one thermoplastic elastomer (B) and c) at least one coupling agent (C); wherein the coupling agent (C) couples the thermoplastic elastomer (B) to the polyoxymethylene (A) and comprises a polyisocyanate; and wherein the molding composition has a melt volume rate (MVR) of less than 3 g/10 min, determined according to ISO 1133 at 190° C. and 2.16 kg; and a Charpy Notched Impact Strength (CNI) at 23° C., determined according to ISO 179-1/1eA (CNI), of higher than 15 kJ/m a complex shear viscosity η
