Abstract
A moulding composition based on linear polyoxymethylene copolymers and customary additives with a melt index MFI (2,16 kg, 190.degree. C.) of .ltoreq.0,8, preferably .ltoreq.0,5 and especially .ltoreq.0,2 g/10 min has an extraordinary high toughness, which eliminates an addition of elastomer modifiers. In its preparation Lewis acids or protonic acids are used as initiators.
